6.0  LIST OF BUGS FIXED IN WINDOWS NT 4.0 SERVICE PACKS 1-4

1.0  INTRODUCTION
=================

This release of Microsoft Windows NT 4.0 Service Pack 4 (SP4) is easy to
apply while Windows NT is running and updates all files that are older than
those included in this Windows NT Service Pack. Service Pack releases are
cumulative and contain all previous Service Pack fixes and any new fixes
created after Service Pack 3.

IMPORTANT: SP4 contains only 40-bit encryption. This release isn't
supported for installation on an existing North American 128-bit
installation of Windows NT 4.0. If you install SP4 on a computer with 128-
bit encryption, system services might fail to start.

IMPORTANT: It's recommended that you stop running any critical services
before you apply Windows NT 4.0 SP4. For more preinstallation
recommendations, see section 2.1, "Before You Install the Service Pack."

1.1  What's New in Service Pack 4
---------------------------------

1.1.1 Active Accessibility Support

Microsoft Active Accessibility (MSAA) is a COM-based standard method
by which a utility program interacts with an application's user
interface (UI). Using MSAA applications can expose all UI elements
and objects with standard properties and methods. SP4 includes five
new application programming interfaces (APIs). These new APIs include:

 - GetGUIThreadInfo
 - GetAncestor
 - RealChildWindowsFromPoint
 - RealGetWindowClassA
 - RealGetWindowClassW

1.1.2 DCOM/HTTP Tunneling

This update allows DCOM client/server communication to cross firewalls over
the HTTP protocol port. The new protocol "Tunneling TCP" is used like other
DCOM protocols. The new moniker type OBJREF is passed in HTML to the
client. The benefits of Tunneling TCP include high performance, use of
existing open ports in the firewall, and control of client access for proxy
administrators. For more information, see http://www.microsoft.com/com.

For instructions on installing Tunneling TCP, see section 3.11, "Installing
COM Internet Services" under User Notes.

1.1.3 Euro Key Patch

The Euro Key Patch is an update to include the new European "euro" currency
symbol. The update supplies the core fonts (Arial, Courier New, and Times
New Roman) and the keyboard drivers.

1.1.4 InternetGroup Management Protocol (IGMP) v2

IGMPv2 allows a computer to inform the router that it's leaving a group.
This update enables the router to determine if there are no more members in
a group and then executes a command to stop forwarding mcast packets on to
the link. This update is useful when users are frequently joining and
leaving groups.

1.1.5 Microsoft File and Print Service for NetWare (FPNW) Support
for Client32

Microsoft File and Print Services for NetWare permits the Windows NT 4.0
Server to act as a NetWare 3.X Server and is able to process file and print
requests from NetWare clients without changing or updating the NetWare
client software. This Service Pack provides an update that allows Windows
NT 4.0 to support NetWare's Client32. This update installs only on those
computers that have the FPNW service already installed.

1.1.6 Proquota.exe

The Proquota.exe is a utility that can be set up to monitor the size of
users' profiles. If an individual user's profile exceeds the predetermined
file limit, the user won't be able to log off of the computer until the
user reduces the size of the file.

1.1.7 Remote Winsock (DNS/Port 53)

Proxies or firewalls will often disable the Domain Name System (DNS) port
number 53 in order to deter external sites from querying the internal DNS
structure. As a result, inbound response packets sent on port 53 can't be
received. SP4 provides a solution to change the Windows NT DNS server port
number and configure it to use a different port number when connecting
outbound.

To enable this feature, a registry value "DWORD" is created. Locate
\services\dns\parameters\SendOnNonDnsPort and set to a non-zero value to go
off port 53. If the value is < 1024 the server can use any port number. If
the value is > 1024 the server will use the port number specified.

1.1.8 Remote Procedure Calls (RPC) Enhancements for Visual Basic (VB)

RPC enhancements for VB have been provided in this release. In VB, a "User
Data Type (UDT)" is added allowing the TypeLib arrangement of structures.
These new user interfaces, IRecordInfo, provide UDT information and a UDT
field for the Access Database.

1.1.9 Routing Information Protocol (RIP) Listener

If you utilize RIP Listener on a computer running Windows NT 4.0, you can
use SP4 to update this component. If you want to install RIP Listener after
you apply SP4, use the following procedure.

To install the RIP Listener:

1. Insert the SP4 CD into the disc drive, and change the folder to \I386
   (or \Alpha).

2. Copy Oemnsvir.wks to D:\<winntsystemroot>\system32\oemnsvir.inf.

3. Click Start, point to Settings, and click Control Panel. Double- click
   Network, and on the Services tab, click Add.

4. In Network Service, select RIP for Internet Protocol, and then click OK.

5. In the Windows NT Setup dialog box, type the path for the location of
   the SP4 files and click OK.

1.1.10 Visual Studio-MICS

This Service Pack includes an update to Visual Studio called Visual Studio
Analyzer Events. Visual Studio Analyzer Events provides a graphical
representation of high-level behaviors and their solutions. Use Visual
Studio Analyzer Events to view graphically simple tables of event logs, the
system's performance, and Windows NT Performance Monitor (NT PerfMon), as
well as other system data.

1.1.11 Year 2000 (Y2K) Fixes

This Service Pack contains fixes for known Year 2000 issues for Windows NT
4.0, including:

 - The User Manager and User Manager for Domains recognize the year 2000 as
   a leap year.
 - The Date/Time Control Panel applet can update the system clock.
 - Find Files supports only numeric character recognition in the decades
   field.
 - Word document properties recognize both 1900 and 2000 as valid centuries
   and support four-digit years.
 - The Dynamic Host Configuration Protocol (DHCP) administrators program
   supports displaying the years between 2000-2009 with a minimum of two
   digits.

For more information, see section 2.4, "Year 2000 Service Pack
Installation."

1.1.12 Compaq Fiber Storage Driver

This driver and .Inf are located in the \Drvlib folder. When installed,
the Compaq fiber storage driver along with the .Inf provides support
for Compaq fiber storage devices. The certified devices are:

 - Compaq Fiber Channel Host Controller/P for PCI.
 - Compaq Fiber Channel Host Controller/E for EISA.

1.1.13 Internet Explorer 4.01 Service Pack 1

Internet Explorer 4.01 Service Pack 1 is located in SP4 in the
\Msie401 folder. Run Ie4setup.exe to install this version of Internet
Explorer on your computer.

1.1.14 Message Queue (MSMQ) for Windows 95 Client

This Service Pack also includes MSMQ Windows 95 Client fixes, located
in the \Support\Msmq.95 folder. Most problems that are mentioned in
section 3.10, "Message Queue (MSMQ) Notes," also apply to Windows 95.
In addition, the Windows 95 MSMQ update fixes a problem causing long
delays with MQOpenQueue() and MQIS operations on offline computers.
This MSMQ Windows 95 update doesn't have an uninstall option.

1.1.15 Option Pack Fixes

This Service Pack release includes Option Pack fixes and enhancements. If
you have the Internet Information Server version 4.0 Option Pack installed,
the Service Pack 4 update program will automatically update the Option Pack
components installed on your computer.

When beginning the installation of the Windows NT Option Pack 4.0 on a
server with Windows NT SP 4.0 and Internet Information Server 3.0, the
following message may appear:

"Setup detected that Windows NT 4.0 SP4 or greater is installed on your
machine. We haven't tested this product on SP4. Do you wish to proceed?"

The Windows NT Option Pack 4.0 is fully tested and supported to run on
servers with the Windows NT Service Pack 4.0. Click Yes to continue Setup.

NOTE: It’s recommended that you reinstall SP4 after you install Windows NT
Option Pack 4.0. Otherwise, an MSMQ MQIS Controller installation won’t work
until the Windows NT Service Pack 4.0 is reinstalled.

   1.1.15.1 Certificate Server

   The Microsoft Certificate Server is a standards-based, highly
   customizable server application for managing the creation, issuance, and
   renewal of digital certificates. Certificate Server generates
   certificates in standard X.509 format. These certificates are used for a
   number of public-key security and authentication applications including,
   but not limited to, server and client authentication under the Secure
   Sockets Layer (SSL) protocol and secure e-mail using Secure/Multipurpose
   Internet Mail.

   The update to Certificate Server includes:

    - Teletex Encoding--Data encoded as teletex in a certificate request
      will be encoded as teletex data in the certificate issued. Formerly,
      this data would have been encoded as Unicode in the certificate
      issued.

    - Serial Number--Serial numbers are generated according to X.509
      standards. These serial numbers are automatically generated, unique,
      and always positive. This is to accommodate restrictive mail clients.

    - Backup/Restore--Specific backup requests are supported, including
      backing up keys and certificates.

    - An update to the default policy module so that mail certificates
      issued are usable by Outlook 98.

    - An update to Certificate Server to fix a problem with certificates
      issued on February 29th of a leap year. Previously, the validity
      period would have the NotBefore and NotAfter dates set to the same
      date. With this update, NotBefore and NotAfter are now set correctly
      in the context of the CA validity for certificates issued on February
      29th of a leap year.

   For information on how to use the keys and certificate backup/ restore
   utility, go to the Knowledge Base at http://support.
   microsoft.com/support/ and search for KB article Q185195.

   This release of Certificate Server doesn’t support certificate
   hierarchies. However, a limited subset of the functions of Certificate
   hierarchies work specifically with Exchange.

   You can get additional information on this from a white paper titled
   "Creating Certificate Hierarchies with Microsoft Certificate Server
   Version 1.0." This is available as a self- extracting .exe file
   (Hier3.exe) on the Microsoft Web site at
   http://support.microsoft.com/support/downloads/LNP279.asp.

   1.1.15.2 Index Server

   Index Server is a content indexing engine that provides full text
   retrieval for Web sites. Index Server requires that Internet Information
   Server be installed.

   1.1.15.3 Internet Information Server (IIS)

   The following Internet Information Server version 4.0 Option Pack
   components are installed on your computer:

   1. Security Enhancements--Support for long file names for access
      restrictions on a file or a folder.

   2. Performance--Improvements on the logging and caching of information.
      These improvements include, but aren't limited to:

       - IIS 4.0 performance on extension mapping.
       - IIS 4.0 memory performance for mapping log files.
       - IIS 4.0 performance in mapping unmapped data files if
         memory configuration is low or stressed.

   1.1.15.4 Message Queue (MSMQ) for Windows NT

   This update to MSMQ includes:

    - Performs cleanup of unused message file space every six hours to
      reduce disk-space usage.

      NOTE: This schedule may be configured via the
      <MessageCleanupInterval> MSMQ registry key (in milliseconds).

    - Clears all obsolete express message files when the MSMQ service
      starts.

    - Enforces case insensitivity with foreign language characters in
      private queue names.

    - Reduces occurrences of duplicate messages in persistent delivery
      mode.

    - Exhibits performance counters for remote queues after a system
      recovery.

    - Correctly shows per-session outgoing messages performance counters.

    - MSMQ MQIS servers refresh cached information every 12 hours.

    - Fixes a problem causing transactional messages to be rejected in some
      cases.

    - Allows specifying external certificates via the MSMQ ActiveX
      components interface.

    - Transactional messages can be read from connector queues after
      restarting the MSMQ connector application.

    - MQSetQueueSecurity for private queue is supported.

    - MQCreateQueue for private queues now works on Windows NT Server 4.0
      Option Pack installations on Microsoft Cluster Server computers.

    - Supports sending Microsoft PowerPoint and Microsoft Word documents
      using ActiveX components.

    - Fails when user attempts the renewal of internal certificates when
      Primary Enterprise Controller (PEC) is unreachable.

    - Machine quota limitation correctly recomputed after restarting the
      MSMQ service.

    - MSMQ COM objects correctly process asynchronous message arrival
      events in multithreaded applications.

    - Improved detection and reporting of corrupted message packets in
      message files that could have resulted in a hung MSMQ service
      previously.

    - Transactional messages sent offline are no longer rejected with a bad
      message class: MQMSG_CLASS_NACK_BAD_DST_Q. The symptom was that such
      messages were immediately routed to the sender's exact dead letter
      queue.

    - Supports sending messages to different computers that have the same
      IP address. This can happen when a server attempts to send messages
      to two different RAS clients that happen to be assigned the same
      address one after the other.

    - Recovers correctly when sending messages from a server to a client
      whose address is no longer valid (e.g., a RAS client that has timed-
      out). Previously, extra message traffic might have been generated.

    - Asynchronous messaging now functions correctly on Japanese Windows 95
      when using the MSMQ COM objects.

    - Fixes a problem in the MSMQ COM objects when referencing the response
      and admin queue properties of a message for queues not explicitly
      refreshed from the MQIS.

    - In Windows 95, calling MQOpenQueue with a DIRECT format no longer
      blocks for a long time.

    - If the Windows NT 4.0 licensing service isn't running, then MSMQ per-
      seat licensing is no longer enforced.

    - A specific call to MQLocateBegin no longer causes an exception on the
      MQIS server. This could have occurred previously when the Label
      restriction specified with an incorrect vt argument (anything other
      than VT_LPWSTR).

    - MSMQ applications can be run by users logged on to local machine
      accounts. Note that this used to work anyway for shadowed local
      accounts -- i.e., for accounts that had "identical" local accounts
      (user name/password) on the server machine. The default security for
      queues created by such users is that everyone is granted full control
      (in particular, read and delete permissions).

    - A new MQIS update/restore utility is supplied that enables
      administrators to seamlessly recover crashed MQIS servers. See
      support\msmq.nt\MQISwizard.doc for more information.

   1.1.15.5 Microsoft Transaction Server (MTS)

   MTS is updated with a new Java Context class. If you're building
   applications using Visual J++, you can use the new Context class instead
   of IObjectContext. The Context class allows you to do the following
   using Visual J++:

    - Declare that the object's work is complete.

    - Prevent a transaction from being processed, either temporarily or
      permanently.

    - Instantiate other MTS objects and include their work within the scope
      of the current object's transaction.

    - Determine whether a caller is in a particular role.

    - Determine whether security is enabled.

    - Determine whether the object is executing within a transaction. See
      the Visual J++ section of the Programmer's Reference for complete
      documentation of the new class.

   1.1.15.6 SMTP, NNTP

   Simple Mail Transport Protocol (SMTP), Network News Transport Protocol
   (NNTP) enhancements are available in this Service Pack. SMTP now
   supports the following services:

    - Multiple virtual servers, or sites.
    - ETRN command for dequeuing mail over dial-up connections.

   To enable this functionality:

   1. Create a text file with the following text:

         set obj = GetObject ( "IIS://localhost/smtpsvc" )
         obj.Put "SmtpServiceVersion", 2
         obj.SetInfo

      NOTE: This is an Active Directory Service Interface (ADSI)
      script that will update a value in the metabase.

   2. Save this file as Enable.vbs.

   3. From a command prompt, type the following and press ENTER:

         cscript enable.vbs

      For more information, go to the Knowledge Base at http://support.
      microsoft.com/support/ and search for KB article Q183476.

      You can also point to specific KB articles using the following
      example:

         http://support.microsoft.com/support/kb/articles/Q151/8/60.asp

1.1.16 Security Configuration Manager (SCM)

Security Configuration Manager (SCM) is an integrated security system that
gives administrators the ability to define and apply security
configurations for Windows NT Workstation and Windows NT Server
installations. SCM also has the capability to perform inspections of the
installed systems to locate any degradation in the system's security. For
further information on SCM, including installation and usage instructions,
refer to Readme.txt in the \Mssce folder.

1.1.17 Web-based Enterprise Management (WBEM)

WBEM/WMI is Microsoft's implementation of Web-Based Enterprise Management
(WBEM), the new standard for representation of management information as
supported by the Desktop Management Task Force. It surfaces important
management data from Windows NT and makes it freely available to any
management tool through a number of well-defined interfaces so that
management of Windows NT becomes much easier (included on CD-ROM only). For
more information on WMI, see http://www.microsoft.com/management/wbem.

WBEM consolidates and unifies the data provided by existing management
technologies. WBEM focuses on solving real enterprise issues by tracking
problem areas from the user/application level through the systems and
network layers to remote service/server instances. For more information,
see http://wbem.freerange.com/.

You can download the Web-Based Enterprise Management Software Developer's
Kit (SDK) at http://wemd/sites/mig/ManagementAndPlanning/Document%20Library1/1/WMIv1/(02.14.2003)%20WBEM%20Competitive%20review.doc.

1.1.18 Microsoft Windows NT Server NetShow Services

SP4 contains an updated version of NetShow Services located on this CD in
the \NetShow folder. NetShow Services enables Internet service providers
(ISPs) and organizations to deliver the highest-quality audio and video at
every bandwidth across the Internet or enterprise networks. This release of
NetShow Services features greatly enhanced audio and video that delivers
the best user experience. Simplified setup, configuration, and
administration of the NetShow server components and tools give ISPs a
reliable and cost-effective platform for hosting large amounts of content.

Consult the NetShow Services information page (\NetShow\ntsp4-ns.htm) for
details on installing and configuring this product. Before installing this
product, you should also carefully review the NetShow Services release
notes at \NetShow\ns-readme.htm.

1.1.19 Microsoft Windows Media Player

Microsoft Windows Media Player replaces Microsoft ActiveMovie as well as
the Microsoft NetShow Player. Windows Media Player has all the features
found in both of the other multimedia players, plus many more. It also
upgrades existing Windows Media Player and ActiveMovie support to provide
convenient access to new Windows Media content. Windows Media Player
supports most local and streaming multimedia file types including WAV, AVI,
QuickTime, RealAudio 4.0 and RealVideo 4.0. The new player takes over the
class IDs of the previous players. After you install the new player,
programs that used the old class IDs will function as usual. Windows Media
Player is located in the \Mplayer2 folder on the compact disc.

1.1.20 Security Privilege Must Be Enabled to View Security Event Log

SP4 includes a bug fix in the Event Log service that requires that the
SE_SECURITY_NAME privilege, also known as the Security privilege, be
enabled in order to view and manage the security event log. By default,
Windows NT grants the privilege to administrators and local System. In
order to take effect however, the privilege must also be enabled in the
program accessing the security event log.

Prior to this change, members of the Administrators group and services
running as local System could open the security log for read or change
access without enabling the Security privilege. If the privilege was
removed from the Administrators group, members of the Administrators group
could still manage the security log. This change enforces the security
model that administrators need to be granted the privilege to manage the
security log; they won't be able to manage the log simply because they are
members of the Administrators group. Administrators can always grant
themselves the Security privilege to manage the security log, however,
although this event can be audited.

For more information, consult the Knowledge Base at http://support.
microsoft.com/support/ and search for KB article Q188855.

1.1.21 Dynamic Host Configuration Protocol (DHCP)

This Service Pack includes several quality improvement fixes to correct
known Dynamic Host Configuration Protocol (DHCP) issues reported for
Microsoft DHCP Server, the DHCP Manager administration tool, and for
Microsoft DHCP-enabled clients running under earlier released versions of
Windows NT 4.0.

These fixes address specific problems fully described in the Q184693
"DHCP/WINS Release Notes for Windows NT 4.0 SP4 Update" article in the
Knowledge Base:

You can obtain the specific article from Microsoft Support Online at
http://support.microsoft.com/support.

1.1.22 Windows Internet Naming Service (WINS)

Windows NT Server includes the following new Windows Internet Naming
Service (WINS) and WINS Manager features:

 - Manual removal of dynamic WINS database records.
 - Multi-select operations for WINS database records.
 - Burst mode handling for WINS servers.

1.1.23 Microsoft Routing and Remote Access Service (RRAS)

SP4 can now be installed on a Windows NT 4.0 system running Routing and
Remote Access Service (RRAS). SP4 will update your RRAS system to RRAS
Hotfix 3.0 components automatically. If you install RRAS after installing
SP4, you must reinstall SP4 to get the updated RRAS files to ensure RRAS
will work properly. For more information on RRAS Hotfix 3.0, see
http://support.microsoft.com/support/kb/articles/Q189/5/94.asp.

1.1.24 PPTP Performance and Security Update

SP4 now includes new performance and security updates to PPTP that greatly
increase data transfer speeds and enhance security. The PPTP client and
server system must both be running the updated files to get the new
benefits. For more information, see http://support.microsoft.com/ 
support/kb/articles/q189/5/95.asp

1.1.25 NTLMv2 Security

SP4 contains an enhancement to NTLM security protocols called NTLMv2, which
significantly improves both the authentication and session security
mechanisms of NTLM. For more information, see
http://support.microsoft.com/support/kb/articles/q147/7/06.asp.

1.1.26 Secure Channel Enhancements

SP4 contains an enhancement to the secure channel protocols used by member
workstations and servers to communicate with their domain controllers and
by domain controllers to communicate with other domain controllers. In
addition to authentication, you can now encrypt and check the integrity of
these communications. For more information, see
http://support.microsoft.com/support/kb/articles/ q183/8/59.asp

1.1.27 IP Helper API (IPHLPAPI)

The IP Helper API provides Windows network configuration and statistics
information to Win32 applications. The public API is available on Windows
NT 4.0 and above, and Windows 95 and above. SP4 updates the API with a new
.dll so that applications can communicate to a TCP/IP stack.

1.1.28 Event Log Service

This Service Pack contains new features in the Event Log Service to assist
how administrators measure the reliability and availability of Windows NT.

The SP4 Event Log Service records three new events in the system event
log that are useful in measuring operating system availability:

 - Clean Shutdown Event (Event ID: 6006)
 - Dirty Shutdown Event (Event ID: 6008)
 - System Version Event (Event ID: 6009)

See section 3.12, "Event Log Service," for more information.

1.1.29 Domain Name Server (DNS) Service

This Service Pack includes several quality improvement fixes to correct
known Domain Name Server (DNS) issues reported for Microsoft DNS Server and
the DNS Manager administration tool. These fixes address specific problems
described in the Q184693 "DNS/DHCP/WINS Release Notes for Windows NT 4.0
SP4 Update" article in the Knowledge Base. You can obtain the specific
article from Microsoft Support Online at http://support.
microsoft.com/support.

1.2  Downloading and Extracting the Service Pack
------------------------------------------------

If you have downloaded this Service Pack from an FTP site or a Web site,
you should read the release notes completely before you extract and install
the Service Pack. For this release, these self-extracting executables are
also located at the root of the CD. They are Sp4alpha.exe for Alpha
processor type systems and sp4i386 for Intel-based systems.

After downloading the Service Pack, you'll have a compressed executable
file on your hard drive. To extract this file and begin the installation
process, for example, type Sp4i386.exe at the command prompt or double-
click the file from Windows NT Explorer. You can also extract the file into
the current folder without launching the installation program by using the
command prompt switch /x (for example, at the command prompt, type sp4i386
/x).

2.0  INSTALLATION INSTRUCTIONS FOR WINDOWS NT 4.0 SERVICE PACK 4
================================================================

Carefully read the installation instructions before you install Service
Pack 4, as they may have changed from previous Service Packs.

2.1  Before You Install the Service Pack
----------------------------------------

Close all active debugging sessions before installing this Service Pack,
otherwise the Update program will be unable to replace system files that
are in use. If a file is in use when you install the Service Pack, a dialog
box will appear in which you can choose to cancel the installation or skip
the file copy. It's recommended you choose to cancel the installation, and
then uninstall SP4. To do this, run Spuninst.exe or click Start, point to
Settings, click Control Panel, double-click Add/Remove Programs, and then
click Uninstall Service Pack 4. Close all active sessions on the system,
and then run Update.exe again to install the Service Pack.

Also, to maximize the ability to recover the system in the event of
installation failure, it's recommended that you do the following before
installing the Service Pack:

1. Update the system Emergency Repair Disk using the Rdisk.exe command with
   the /s switch.

2. Perform a full backup of the system, including the system registry
   files.

3. Disable any nonessential third-party drivers and services (that is,
   drivers and services that aren't required to boot the system).

4. Contact the original equipment manufacturer (OEM) that provided the
   driver or service for the updated versions of the file(s).

5. Restart the computer and check Event Viewer to ensure there are no
   system problems that could interfere with the installation of SP4.

Users of NEC Versa 6050 or 6200 Series notebook computers, with Windows NT
version 4.0 preinstalled, should select "Yes" when SP4 Update.exe prompts
you to replace the hal.dll file.

If your computer contains SystemSoft Card Wizard version 2.x or earlier,
you must obtain SystemSoft Card Wizard version 3.00.01 or greater before
installing Windows NT 4.0 Service Pack 4. Otherwise, your operating system
will no longer function. Contact SystemSoft at http://www.systemsoft.com
for further details.

Advanced Power Management isn't supported by Windows NT 4.0. As a result,
it's recommended that you remove Advanced Power Management features before
installing this Service Pack.

Power Management Utilities may not work on Windows NT 4.0 Service Pack 4.
Contact the vendor of your Power Management Utilities for an updated
version to work with Windows NT 4.0 SP4.

Do not install SP4 without the Silicon Graphics companion software. SP4
requires additional files to update your Silicon Graphics system. For these
necessary files, visit the Silicon Graphics Web site at
http://support.sgi.com/nt.

2.2  Installing the Service Pack
--------------------------------

To install the Service Pack from the CD

1. Insert the Service Pack CD into your CD-ROM drive.

2. If a Web page opens in your browser after you insert the CD, click
   Windows NT Service Pack, and then click Install Service Pack.

3. When you're asked whether you want to open the file Spsetup.bat or save
   it to disk, click Open and then follow the instructions that appear on
   the screen.

   NOTE: To use the uninstall feature of this Service Pack, you must create
   an Uninstall folder during the initial installation.

4. If a Web page doesn't automatically open when you insert the CD, open
   the Command Prompt window and change the folder to the drive letter
   associated with the CD-ROM drive.

5. Change the folder to \I386\Update or \Alpha\Update (depending upon
   whether you have an x86 or Alpha CPU), and type UPDATE.

6. Follow the instructions that appear on the screen.

If SP4 doesn't install after you click Install Service Pack 4 from the CD,
or your browser doesn't automatically display installation instructions
when you insert the CD into your CD-ROM drive, start the Service Pack
install process manually from the CD. For more information, see "To install
the Service Pack from the CD" mentioned earlier in this section.

NOTE: To use the uninstall feature of this Service Pack, you must create an
Uninstall folder during the initial installation.

To install the Service Pack from a network drive

1. Run the command to connect to the network drive that has the Service
   Pack files.

2. Change the drive letter to that network drive.

3. Change the folder to \I386\Update or \Alpha\Update (depending upon
   whether you have an x86 or Alpha CPU), and then type UPDATE.

4. Follow the instructions that appear on the screen.

NOTE: It's recommended that you choose to create an Uninstall folder
the first time you install the Service Pack.

To install the Service Pack from the Internet

Using a Web browser (such as Internet Explorer 3.0 or later), visit
http://support.microsoft.com/support/ntserver/ content/servicepacks/ or
http://support.microsoft.com/support/downloads/. Click the Install Service
Pack 4 option to install SP4 on your computer. This Web page automatically
detects which files need to be updated and then copies the appropriate
files to a temporary folder on your computer. It then installs only those
files that are needed to update your computer.

NOTE: If you use Web browsers other than Internet Explorer 3.0 or later,
you may be unable to install the Service Pack through this update method.
If you are unable to install the Service Pack using this option, download
the entire Service Pack from the Internet onto your computer and run
update.exe locally.

There are installation switches that can be used with Update.exe. The
following syntax help is available by typing update /?:

UPDATE [-u] [-f] [-n] [-o] [-z] [-q]

      -u Unattended mode
      -f Forces other apps to close at shutdown
      -n Do not back up files for uninstall
      -o Overwrite OEM files without prompting
      -z Do not reboot when installation is complete
      -q Quiet mode - no user interaction

2.3  Service Pack Uninstall
---------------------------

This Service Pack contains an uninstall feature that you can use to restore
your system to its previous state.

To enable the uninstall option, run Update.exe. A subfolder in your Windows
NT folder named Uninstall will be created. This requires at least 80
megabytes (MB) of free space on the drive on which Windows NT is installed.
This is 40 MB for the uninstall folder and 40 MB for the Service Pack
updated system files.

To uninstall SP4, double-click the Add/Remove Programs control panel.
Select Windows NT 4.0 Service Pack 4, and click Add/Remove. If this option
isn't available, run Spuninst.exe from the \%systemroot%\ 
$NtServicePackUninstall$\spuninst\ folder.

NOTE: If you install any applications or services that require SP4 or have
bug fixes contained in SP4, uninstalling SP4 could adversely affect those
applications.

If you want to uninstall SP4, the drive letter for the boot drive must be
the same as when you installed SP4. If you change the drive letter for the
boot drive, you can't uninstall SP4.

To uninstall Service Pack 2 and Service Pack 3, you had to run Update.exe
and then select "Uninstall a previously installed Service Pack." This
returned your system to its previous state. After your system restarted,
the Update.exe program replaced the files updated by the Service Pack with
most of the files from the previous installation and returned most of your
registry settings to what they were before that Service Pack was installed.

NOTE: If you uninstall SP4 on a system that previously had Service Pack 3
(without Internet Explorer 4.0) installed on it, cryptography won't work
correctly after the uninstall completes. To work around this issue,
reinstall Service Pack 3 after you have uninstalled SP4.

Uninstalling SP4 won't uninstall new versions of CryptoAPI and SChannel.

NOTE: If you plan to install a previous Service Pack after uninstalling
SP4, take note of the following important precaution. SP4 modifies the
Security Account Manager (SAM) database and the Security database such that
older versions of the Samsrv.dll, Samlib.dll, Lsasrv.dll, Services.exe,
Msv1_0.dll and Winlogon.exe files no longer recognize the database
structure. Therefore, the uninstall process doesn't restore these files
when uninstalling SP4. If you install a prior Service Pack (for example,
Service Pack 3) after uninstalling SP4, click "No" on the "Confirm File
Replace" dialog boxes that ask if you want to overwrite Samsrv.dll and
Winlogon.exe. If you overwrite the newer files with these older versions,
you'll be unable to log on to the system.

NOTE: If you're reinstalling SP4 after installing new software or hardware,
you must choose to create a new Uninstall folder. To retain your ability to
back out to a bootable configuration, copy the current Uninstall folder to
a safe location before running the SP4 installation program.

2.4  Year 2000 Service Pack Installation
----------------------------------------

Windows NT Service Pack 4 contains fixes for known Year 2000 issues in the
Windows NT 4.0 operating system.

To install the Year 2000 Service Pack from compact disc:

Installing the Service Pack using Update.exe will update all necessary

you if any additional Microsoft components that require updating to resolve
known Year 2000 issues in the Windows NT 4.0 operating system. Follow the
procedure below to update your computer to resolve known Year 2000 issues.

Run the Y2ksetup.exe program located in the \I386\Update (for x86-based
computers) or \Alpha\Update (for Alpha-based computers) folders on the
Service Pack 4 compact disc. This program automatically updates operating
system components as detected to resolve known Year 2000 issues.

Note that this installation will require the system to be restarted one or
more times. There is no uninstall option available for Y2ksetup.exe.

To install the Year 2000 Service Pack via the Web or FTP:

Install the base Service Pack from one of the locations below to your
computer:

    http://www.microsoft.com/downloads/details.aspx?familyid=8b3a1f23-c17c-4dc9-96ea-cf8652acf2d4&amp;displaylang=en 

   http://support.microsoft.com/support/downloads/ 

The download program will automatically detect which files need to be
updated. Once prompted with the File Download dialog, select "Run this
program from its current location" to perform a patched installation. This
will also detect and inform you if any additional Microsoft components
require updating to resolve known Year 2000 issues on your Windows NT 4.0
operating system. Follow the procedure below to resolve known Year 2000
issues.

Download the Year 2000 Service Pack (y2ksp4i.exe or y2ksp4a.exe) from one
of the locations below to your computer:

   ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/ 

    http://www.microsoft.com/downloads/details.aspx?familyid=8b3a1f23-c17c-4dc9-96ea-cf8652acf2d4&amp;displaylang=en 

   http://support.microsoft.com/support/downloads/ 

Run the self-extracting executable to expand the package. Run Y2ksetup.exe
from \I386\Update (for x86-based computers) or \Alpha\Update (for Alpha-
based computers) folder at the target location. This program automatically
updates operating system components as detected to resolve known Year 2000
issues.

Note that this installation will require the system to be restarted one or
more times. There is no uninstall option available for Y2ksetup.exe.

If you need to reinstall this Service Pack, run Update.exe from the
\I386\Update or \Alpha\Update folders. It isn't necessary to uninstall the
Service Pack previous to running Update.exe more than once on the same
system. Use \I386\Update\Y2ksetup.exe or \Alpha\Update\Y2ksetup.exe to
resolve known Year 2000 issues in the Windows NT 4.0 operating system.

There are installation switches that can be used with Y2ksetup.exe.
The following switches are available:

Y2KSETUP [-q] [-d]
      -q silent mode installation
      -d display only (does not install, only displays those operating
         system components on the computer that contain known Year 2000
         issues)

2.4.2 Site Server Express 3.0

There are known Year 2000 issues in the following components of Site Server
Express 2.0:

 - Content Analyzer
 - Usage Analyst

Installing Site Server Express 3.0 directly from the Web or from the CD
doesn’t remove these components from your computer. You must install
Y2ksetup.exe to remove these components from your computer and install Site
Server Express 3.0, which contains an update for:

 - Usage Analyst
 - Posting Acceptor

An updated version of the Content Analyzer will be available for download
from the Windows NT Service Pack 4.0 Web site.

Known Site Server Express 3.0 setup issues:

 - When Y2KSetup installs Internet Explorer 4.01 SP1 and Site Server
   Express 3.0, two IIS virtual roots that are required by Posting Acceptor
   aren't created. It's recommended that you reinstall Site Server Express
   3.0 by running Ssx.exe from the \Ssx folder on the CD.

2.4.3 FrontPage Server Extension Year 2000 Issues

Releases of FrontPage 1.0, FrontPage 1.1 and FrontPage 97 are not Year
2000 compliant. Releases of FrontPage 98 resolve known Year 2000 issues.
If you have NTOP installed, you will have FrontPage 98 Server Extensions.
It's possible to have two or more versions of the FrontPage Server
Extenders on your computer at one time. The installation of a version
that isn't Year 2000 ready doesn't mean that you are actively running
that version.

To determine which version of the FrontPage Server Extenders are actively
in use on computers with FrontPage 98 or earlier

 - Run the FrontPage Server Administrator (Fpsrvwin.exe).

 - Click on each of the Web servers or virtual servers listed in the
   box in the upper left area, which have been configured with the
   FrontPage Server Extenders.

 - The version number of the FrontPage Server Extenders is displayed
   to the right of the list. Version numbers where the first digit is
   3 or greater resolve known Year 2000 issues (e.g. 3.0.2.1706).

If the first digit of the version number is a 1 or 2, then you should
download and install the latest version of the FrontPage Server Extenders.
Refer to http://www.microsoft.com/frontpage/ for details on the latest
available version is and how to download.

2.4.4 IBM PS/1 ValuePoint

There are known Year 2000 issues for Windows NT version 4.0 on 2.4.4 IBM
PS/1 ValuePoint computers. To fix these known issues, you must upgrade
Ntdetect.com in order to resolve known Year 2000 issues in older versions.

From the \Ps1 folder on the CD, copy Ntdetect.com to the root of your
primary boot partition on your computer. You do not need to reboot.

For more information, go to the Knowledge Base at http://support.
microsoft.com/support/ and search for KB article Q194301.

For Year 2000 issues regarding Microsoft products or definitions regarding
Year 2000 compliance, as used herein, see our Web site at
http://www.microsoft.com/windows95/downloads/contents/wurecommended/s_wufeatured/win95y2k/default.asp?site=95.

3.0  USER NOTES
===============

This section covers information that is specific to this Service
Pack release.

3.1  Emergency Repair Disk
--------------------------

If you use the Windows NT Emergency Repair Disk to repair your Windows NT
system, which requires you to supply the original Windows NT media at some
time after you install Service Pack 4, you'll need to reinstall SP4 after
the repair is completed. This is because the Emergency Repair Disk repairs
your system by restoring your original Windows NT 4.0 system files. After
the repair is completed, follow the Installation Instructions (Section 2.0)
to reinstall SP4. For more information on using the Windows NT Emergency
Repair Disk utility, go to the Knowledge Base at
http://support.microsoft.com/support/ and search for KB article Q146887.

NOTE: To use the Emergency Repair Disk utility, you must have the updated
version of Setupdd.sys. The updated version is contained in SP4. To update
your version of Setupdd.sys, copy Setupdd.sys from the Service Pack to your
Windows NT 4.0 Setup Disk 2 from the original product media. This will
replace the older version of Setupdd.sys with the updated version. For more
information, consult the Knowledge Base at
http://support.microsoft.com/support/ and search for KB article Q158423.

3.2  Adding New Components to the System
----------------------------------------

If you change or add new software or hardware components to your system
after you install SP4, you'll need to install the SP4 again. This is
because the files included on the original Windows NT 4.0 media may not be
the same as the files on the Service Pack CD. You can't install new
components, such as a new keyboard or printer driver, directly from the
Service Pack media. You must install new components from the original
product media and then reinstall the Service Pack.

For example, if you install the Simple Network Management Protocol (SNMP)
service after installing SP4, you'll need to reinstall the Service Pack. If
you fail to do so, you'll receive the error message "Entrypoint
SnmpSvcGetEnterpriseOID could not be located in Snmpapi.dll." This is
because some of the files in the SNMP service have been updated in the SP4
and you have a version mismatch. Reinstalling the Service Pack fixes the
problem by copying the newer versions of the files to your system.

NOTE: SNMP security provides the ability to set a permission level on the
SNMP agent computer. The permission level determines how the SNMP agent
computer will process requests from an SNMP community.

3.3  Installing Symbol Files from the CD
----------------------------------------

Each program file in Windows NT has a corresponding symbol file that is
used to find the cause of kernel STOP errors. The symbols for SP4 files are
compressed in self-extracting executables named Sp4symi.exe and
Sp4syma.exe, for Intel and Alpha respectively. To install the symbol files
corresponding to the new binaries in SP4, run the executable and when
prompted, specify the path to the location of the previous version's
symbols (for example, c:\winnt\symbols\). This copies the SP4 .dbg files
over the existing versions of these files.

For more information about debugging in Windows NT, see Chapter 39,
"Windows NT Debugger," in the Microsoft Windows NT 4.0 Workstation Resource
Kit.

3.4  Hardware Compatibility with Windows NT 4.0
-----------------------------------------------

3.4.1 Video Drivers

Due to incompatibilities between the ATIRage drivers and Service Pack
setup, the files Ati.sys and Ati.dll haven't been included with SP4. Any
ATI drivers currently installed on your system will still function
normally.

If you install SP4 over SP3 on a computer that has a Number Nine Visual
Technologies Imagine 2 video card and drivers installed, you may experience
some loss of functionality in the video driver, such as loss of any
resolutions requiring 256 or more colors. If you uninstall SP4 and revert
to SP3, the Imagine 2 card may be unable to display 256 colors or higher.
There is no known resolution for either of these two issues because
reinstalling the Imagine 2 video drivers doesn’t restore the lost
functionality. Number Nine is aware of this issue and is working on a fix.

3.4.2 Dell Latitude Systems

If you're running Windows NT 4.0 on a Dell Latitude portable computer, your
Dell-supplied Softex Advanced Power Management and PC Card Controller
services (versions 2.0 and above) will continue to function after you
install SP4. Softex version 1.0 will stop functioning after SP4
installation. To update your system for SP4, install version 2.19 or later
of the Softex utilities, available from http://support.dell.com/ filelib/.
Your computer will become unusable if you reinstall any version of Softex
prior to 2.19 after installing SP4.

3.4.3 Softex/Phoenix Utilities

If you're using any of the following Softex Incorporated or Phoenix
Technologies utilities, you may encounter problems running SP4:

 - Softex PC Card Controller, or Phoenix CardExecutive for Windows NT
 - Softex Power Management Controller, or Phoenix APM for Windows NT
 - Softex Docking Controller, or Phoenix NoteDock for Windows NT
 - Softex DeskPower Controller, or Phoenix DeskAPM for Windows NT

Follow these guidelines:

1. Obtain the version number of the utilities you're using.

2. You must be running version 2.19 or later of the Softex or Phoenix
   utilities to avoid problems with SP4. Don’t install or reinstall
   any version of Softex or Phoenix utilities earlier than 2.19 on
   your system, or your system might not boot. For more information,
   visit the Softex Incorporated Web site at http://www.softexinc.com
   or Phoenix Technologies at http://www.phoenix.com.

3.4.4 255 SCSI Logical Unit Support

Windows NT 4.0 detects only the first 8 logical units on a SCSI device. To
work around this limitation, install SP4 and add the following key in the
registry:

   \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
   \[Driver Service Key]\Parameters\Device[N]

      LargeLuns: REG_DWORD: 0x1

where [Driver Service Key] is your SCSI driver name and [N] is the SCSI
bus number.

3.4.5 IBM PS/1 ValuePoint

There are known Year 2000 issues for Windows NT version 4.0 on this
computer. It's necessary to upgrade Ntdetect.com in order to resolve known
Year 2000 issues in older versions.

From the \Ps1 folder on the CD, copy Ntdetect.com to the root of your
primary boot partition on your computer. You do not need to reboot.

For more information, go to the Knowledge Base at http://support.
microsoft.com/support/ and search for KB article Q194301.

3.4.6 SystemSoft Card Wizard

If your computer contains SystemSoft Card Wizard version 3.x and you have
installed SP4, you may have lost socket services functionality. To
workaround this issue reinstall SystemSoft Card Wizard version 3.x or
higher after installing Service Pack 4. Or you can copy Pcmcia.sys from the
Service Pack 4 Uninstall folder, $ntservicepacekuninstall$, to the
\%systemroot%\System32\Drivers folder on your computer. Reboot the
computer.

3.5  DIGITAL Alpha Notes
------------------------

3.5.1 Using Remotely Possible 32 with Matrox Millennium Display Adapter

If you use Remotely Possible 32 on an Alpha with a Matrox Millennium
display adapter, don't use the Matrox drivers. Otherwise, your computer
bluescreens after rebooting. You must use VGA-compatible display adapter
drivers to use Remotely Possible 32.

3.5.2 Lotus Notes 4.5

If you want to use Lotus Notes and Internet Explorer 4.01 on an Alpha
computer that runs Windows NT 4.0, you must follow this sequence when
installing SP4:

1. If you have Internet Explorer 4.01 on your computer, uninstall it.

2. Install SP4.

3. Install (or reinstall) Lotus Notes.

4. Install Internet Explorer 4.01 from the SP4 CD. This problem will be
   fixed in a future release.

3.5.3 Alpha Fixes in SP4

These notes describe problems on Alpha systems that have been resolved
since the Windows NT 4.0 Service Pack 3 release.

NOTE: Windows NT 4.0 SP4 ships with HAL Revision D. This revision is also
currently available from Compaq.

   3.5.3.1 System Hangs on Alpha Systems with Only One Processor Physically
   Present

   The following Alpha systems, with only one processor physically present,
   no longer hang when booted:

      AlphaServer 4x00
      AlphaServer 1200
      AlphaStation 1200
      DIGITAL Server 5000
      DIGITAL Server 7000

   3.5.3.2 Clock Interrupt Period Changed from 7.5 ms to 10 ms

   In Windows NT 4.0 SP4, the effective clock interrupt period on the
   following systems was changed from 7.5 ms to 10 ms:

      AlphaServer 4x00
      AlphaServer 1200
      AlphaStation 1200
      DIGITAL Server 5000
      DIGITAL Server 7000

   This change will provide parity with Intel systems and alleviate
   performance anomalies caused by assumptions of 10 ms for the
   resolution for timers (which is equal to the clock interrupt period).

   3.5.3.3 Pyxis Error Registers

   HAL Revision D, which ships with Windows NT 4.0 SP4, supports updated
   Pyxis error registers, which provide more meaningful information during
   hardware crashes.

   3.5.3.4 Peer-to-Peer DMA Transfers

   This Service Pack, together with the current AlphaBIOS firmware, now
   allows peer-to-peer DMA transfers.

   3.5.3.5 PCI Devices with 256 MB of Memory or Greater

   The following Alpha platforms now support PCI devices with 256 MB of
   memory or greater for memory-mapped I/O:

      AlphaServer 1000 5/xxx
      AlphaServer 1000A 5/xxx
      AlphaServer 800 or Digital Server 3000
      AlphaStation 600
      AlphaStation 500
      Alpha XL 3xx

   3.5.3.6 Alpha Machines Sometimes Hang When Rebooting

   The following systems no longer hang during an attempted reboot:

      AlphaServer 4x00
      AlphaServer 1200
      AlphaStation 1200
      DIGITAL Server 5000
      DIGITAL Server 7000

   3.5.3.7 I/O Performance Degradation or a Hung Machine Under Heavy I/O

   Loads On Alpha machines with heavy I/O loads, certain device drivers
   consumed too many DMA map registers. This sometimes caused poor I/O
   performance or a hung machine. SP4 allows a greater number of DMA map
   registers.

   3.5.3.8 Crashes on Alpha systems with STOP Code 0x0A

   Minor "correctable" hardware errors no longer generate crashes with STOP
   code 0x0A on following machines:

      AlphaServer 1000 5/xxx
      AlphaServer 1000A 5/xxx
      AlphaServer 800 or Digital Server 3000
      AlphaStation 600
      AlphaStation 500
      AlphaStation 600A
      Alpha XL 3xx

   3.5.4 DIGITAL Ultimate Workstation 533

   SP4 won't update the Hal.dll file on the system because Hal.dll is
   marked as an OEM file. To work around this, you must manually copy
   Halrawmp.dll from SP4 to your system. To do this, first locate the
   Hal.dll file on the system (in the OSLOADER subfolder), and then copy
   Halrawmp.dll from SP4 to this folder, renaming it Hal.dll.

   3.5.5 Installation Fails on Alpha Machines with Windows NT Option Pack
   1.0 Installed

   Security Configuration Manager (SCM) doesn't install on Alpha machines
   that have the Windows NT Option Pack 1.0 for Alpha installed. This is
   because the Mfc42u.dll file installed by the Windows NT Option Pack
   isn't compatible with SCM.

   To work around this, replace Mfc42u.dll installed by Windows NT Option
   Pack 1.0 for Alpha with Mfc42u.dll from the Windows NT4.0 CD or from
   Visual C 6.0. This may cause problems with the applications in the
   Windows NT Option Pack 1.0 for Alpha. This will be fixed in the next
   release of Windows NT.

3.5.4 Microsoft Transaction Server and Distributed Transaction Coordinator

The file TestOracleXAConfig.exe isn't automatically installed on DEC Alpha-
based computers. If you are installing Windows NT 4.0 SP4 on an Alpha-based
computer and will be using Microsoft Transaction Server (MTS) or the
Distributed Transaction Coordinator (DTC) with an Oracle or XA- compliant
database, you must manually copy this file from the CD-ROM to the
%sysroot%\system32 folder on your hard drive. The symbol %sysroot%
represents the installation folder for Windows NT. For example, if your
installation folder is C:\Winnt, you would copy it to C:\Winnt\Wystem32.

TestOracleXAConfig.exe is located in the \Alpha folder on the Windows NT
4.0 SP4 CD-ROM.

If you are installing Windows NT 4.0 SP4 on an Intel-based computer,
TestOracleXAConfig.exe is automatically installed during Setup.

3.6  Running Windows NT Administrative Tools from Remote Server
---------------------------------------------------------------

In order to run administrative tools from a remote server, you must
upgrade the remote server to Service Pack 4. If you attempt to run
administrative tools from a remote machine that hasn't also been
upgraded to Service Pack 4, they will fail to load or won't function
properly.

3.7  CryptoAPI and Authenticode
-------------------------------

The Authenticode environment won't be set up correctly for existing user
accounts on upgrades from Windows NT 4.0 systems running Internet Explorer
3.02. This doesn't affect new user accounts created on the system. Also,
upgrades from Windows NT 4.0 systems with Internet Explorer 4.0 or later
aren't affected.

Each user needs to enter the following command line in a command prompt
window before they use Authenticode:

   setreg 1 false 2 true 3 false 4 false 5 true 6 false 7 true 8 false 9
   false 10 false

Setreg.exe isn't part of SP4; you can download it as part of the CryptoAPI
tools. You can install the latest CryptoAPI tools (Internet Explorer 4.0 or
later) from the Platform SDK on MSDN.

The CryptoAPI tools (also known as Authenticode Signing tools) that were
released for Internet Explorer 3.02 are no longer supported. Tools released
for Internet Explorer 4.0 will continue to work on Service Pack 4.

If you install SP4 on a system with Internet Explorer 4.0 or later and then
uninstall Internet Explorer, newer CryptoAPI components will be partially
uninstalled. This problem doesn't affect the system if Internet Explorer
4.0 was installed after SP4. Reinstall SP4 after uninstalling Internet
Explorer for full functionality.

To ensure proper CryptoAPI functionality, it’s recommended that you install
Internet Explorer 3.02 or later before you install SP4. The following is a
list of known problems when Internet Explorer 3.02 or later is installed
after SP4:

 - Certain CryptoAP2 networking functions have a dependency on Wininet.dll
   and may fail if Wininet.dll isn't on the system. To work around this,
   install Internet Explorer 3.02 or later before installing SP4.

 - Certificate revocation checking fails if you install Internet Explorer
   4.0 after you install SP4. To fix this, reinstall SP4 after installing
   Internet Explorer 4.0. This will be fixed in a future release of
   Internet Explorer.

 - Certain CryptoAPI-related file extensions (.Cer, .Crt, and .Der) aren't
   registered correctly when Internet Explorer 4.0 is installed after SP4.
   To restore the file extension registration, run the following command
   line:

      Regsvr32.exe cryptext.dll

This will be fixed in a future release of Internet Explorer.

3.8  Uninstalling Internet Explorer
-----------------------------------

On a system that had Internet Explorer 4.0 or later installed and then had
SP4 applied, uninstalling Internet Explorer will partially uninstall newer
CryptoAPI components. Reinstall SP4 after uninstalling Internet Explorer.
This problem doesn't affect the system if Internet Explorer was installed
after SP4.

3.9  Certificate Server Notes
-----------------------------

3.9.1 Known Problems and Limitations:

1. Be sure to consult the release notes for the Certificate Server
   version 1.0 as shipped with the Windows NT Option Pack. Also
   consult the QFE update release at ftp://ftp.microsoft.com/bussys/ 
   iis/iis-public/fixes/usa/certserv.

2. Do not perform an initial installation of Certificate Server on
   February 29th of a leap year. The validity period for the server
   will be set incorrectly. To work around this, set the machine
   time to the day before (February 28th), perform the installation,
   and then reset the machine time back to February 29th. There
   is no problem issuing certificates on February 29th, once the
   certificate server is successfully installed (as noted above).

3. If you install Certificate Server on top of SP4, you may receive
   a "Some system services could not start" error message upon
   system startup. Click OK to continue, and check the Event Viewer
   log for the specific error.

   Event ID: 7000
   Source: Service Control Manager
   Description: The Certificate Authority service failed to start due
   to the following error: The service did not respond to the start or
   control request in a timely fashion.

   Event ID: 7009
   Source: Service Control Manager
   Description: Timeout (120000 milliseconds) waiting for service to
   connect.

   There are no workarounds for this problem.

3.9.2 Virtual Directory Attributes for Certificate Server

IIS enforces the application attribute of virtual directories in such
a way that the Certificate Server's administration Web pages fail.
This failure appears in the form of database access errors that are
identified by an E78 access failure code. You will be unable to access
the Certificate Server log and queue from the administration Web pages.
To work around this problem, make sure that the application attribute
for the Certificate Administration (CertAdm) folder is applied.

To apply the application attribute for CertAdm folder:

1. Click Start, point to Programs, point to Windows NT 4.0
   Option Pack, point to Microsoft Internet Information Server, and
   then click Internet Service Manager.

2. In MMC, open the left pane entries until the Default Web Site is
   visible.

3. Double-click the Default Web Site. The right pane now contains the
   first level of virtual directories for the Web server.

4. Right-click the CertAdm virtual directory.

5. Click Properties.

6. In the Application Settings section of the Virtual Directory tab,
   click Create.

7. Click Apply, and then click OK.

3.9.3 Invalid Hash Algorithm Accepted on Installation

During Certificate Server installation, don't select HMAC as the hash
algorithm the Certificate Server should use when issuing certificates.
Although HMAC is among the selections on the optional Advanced Settings
page, this isn't a valid use of this algorithm. If HMAC is selected,
installation of the Certificate Server will fail.
For more information about Certificate Server, consult the Microsoft
Knowledge Base.

3.10  Internet Information Server 4.0, Secure Sockets Layer and Root
Certifying Authority Certificates, and the IISCA.EXE Tool
--------------------------------------------------------------------

If you use Internet Information Server 4.0 (IIS) with secure sockets layer
(SSL) and you have installed a root certifying authority certificate (other
than those issued by well-known third parties, such as Verisign, Thawte
Consulting, or Microsoft), you may need to reinstall the affected root
certifying authority certificates after you install SP4. You need to do
this if you're using Microsoft Certificate Server 1.0, which shipped with
the Windows NT Option Pack.
