Microsoft (R) KB824146 Scanner Version 1.00.0257 for 80x86

The purpose of KB824146Scan.exe is to audit Windows systems over the network
for KB824146 and KB823980patch compliance. KB824146Scan.exe allows
administrators to quickly scan enterprise networks for unpatched systems.

Usage: KB824146Scan.exe [/?] [/i:input_file] [/l[:log_file]] [/n]
                        [/o:out_file] [/r] [/t:timeout] [/v] target ...

Targets can take any of the following forms:

    a.b.c.d             - IP address
    a.b.c.d-i.j.k.l     - IP address range
    a.b.c.d/mask        - IP address with CIDR mask
    host                - unqualified hostname
    host.domain.com     - fully-qualified domain name
    localhost           - check local machine

Targets can be specified on the command line & in user-specified input files.
The format of the input file is one target per line.

KB824146Scan.exe maintains a log file in the current directory if the /l
switch is specified on the command line. (Otherwise output is only sent to the
screen.) The log files will take the form of KB824146Scan_YYMMDD[a-z][a-z].log,
where YY is the two digit year, MM is the two digit month, and DD is the two
digit day. The [a-z][a-z] will be appended to the log file name as additional
scans are completed on the same day. Please note that the log output will only
contain essential information. To capture full information, please specify the
/v switch for verbose logging.

KB824146Scan.exe will create a list of vulnerable systems (unpatched as well
as those with KB823980 installed) in the current working directory. The log
files will take the form of Vulnerable_YYMMDD[a-z][a-z].log, where YY is the
two digit year, MM is the two digit month, and DD is the two digit day. The
[a-z][a-z] will be appended to the log file name as additional scans are
completed on the same day. Its name can be changed with the /o switch.

KB824146Scan.exe will resolve IP addresses to DNS names if the /r switch is
given on the command line. This may incur a performance penalty if your DNS
servers are slow in responding.

KB824146Scan.exe will resolve IP addresses to NetBIOS names if the /n switch
is given on the command line. This may incur a performance penalty if the
remote NetBIOS connection is slow in responding.

KB824146Scan.exe has a default timeout of 5 seconds, which should be fine
for most networks. If your network is slow or has IPSec enabled then you
might want to increase the timeout to 10 seconds or more. Use /t to specify
the number of seconds for the timeout.

Error Messages, Status, and Statistics

• An "unpatched" status indicates that the host that you scanned is a Windows host but that the host does not have the 823980 (MS03-026) and the 824146 (MS03-039) security patches installed. To help protect this computer, you must install the 824146 (MS03-039) security patch.
• A "patched with KB823980" status indicates that the host was scanned and that host has the 823980 (MS03-026) security patch installed. The computer does not have the 824146 (MS03-039) security patch installed. To help protect this computer, you must install the 824146 (MS03-039) security patch.
• A "patched with KB824146 and KB823980" status indicates that the host was scanned and that the host has the 823980 (MS03-026) and the 824146 (MS03-039) security patches installed.
• A "host unreachable" error message indicates that no host is present at the specified Internet Protocol (IP) address. Additionally, black hole routers, or firewalls that drop packets, such as Internet Connection Firewall (ICF), also return the "host unreachable" error message.
• A "DCOM is disabled on this host" status indicates that DCOM has been disabled on the target host computer. DCOM may have been disabled to help protect against the vulnerabilities that are addressed by the 823980 (MS03-026) and the 824146 (MS03-039) security patches.

• A "address is not valid in this context" or a "connection failure" error message indicates there was some problem connecting to the remote computer. To determine whether the target computers have been patched, you must manually inspect them.
• A "connection refused" error message indicates either that no service is listening on TCP port 135 or that TCP port 135 is being filtered (either by the Windows TCP/IP stack or by a firewall or a router). To determine whether the target computers have been patched, you must manually inspect them.
• A "this host needs further investigation" error message indicates that there was some problem scanning the remote host. To determine whether the target computers have been patched, you must manually inspect them.
• A "connection failure, error 67 (0x00000043)" error message indicates that the network name cannot be found. To determine the cause of similar error messages, type the following at the command prompt, where nn is the decimal error number:
  net helpmsg nn
• The "Patched with KB824146 and KB823980" statistic is a count of the target computers that were marked with the status message "patched with KB824146 and KB823980."
• The "Patched with KB823980" statistic is a count of the target computers that were marked with the status message “patched with KB823980.”
• The "Unpatched" statistic is a count of the target computers that were marked with the status message "unpatched."
• The "TOTAL HOSTS SCANNED" statistic is a total of the "Patched with KB824146 and KB823980," the "Patched with KB823980," and the "Unpatched" statistics.
• The "DCOM Disabled" statistic is a count of the target computers that were marked with the status message "DCOM is disabled on this host."
• The "Needs Investigation" statistic is a count of the target computers that were marked with the status message "this host needs further investigation."

Log Files That the KB824146Scan.exe Tool Creates

• KB824146Scan_YYMMDD[a-z][a-z].log: This log file contains information that is similar to the information in the "Sample Output" section of this article.
• Vulnerable_YYMMDD[a-z][a-z].log: This log file contains a list of the IP addresses for computers on your network that do not have the 824146 (MS03-039) security patch installed. You can use the Vulnerable_YYMMDD[a-z][a-z] file without modification as the input file (Ipfile.txt) for the Patchinstall.vbs script that is described in Microsoft Knowledge Base article 827227. If you run KB824146Scan.exe more than one time a day to perform a scan, letters [a-z][a-z] are added to the Vulnerable_YYMMDD[a-z][a-z] file name after the date. For example, if you run KB824146Scan.exe five times on August 21, 2003, the following log files are created in this order:
  1. Vulnerable_030821.log
  2. Vulnerable_030821a.log
  3. Vulnerable_030821b.log
  4. Vulnerable_030821c.log
  5. Vulnerable_030821d.log
  For the sample output that is described in the "Sample Output" section in this article, the Vulnerable_YYMMDD[a-z][a-z].log log file would contain the following entries:
  10.1.1.2
  10.1.1.8

Known Issues

• If remote access or file sharing is enabled, the KB824146scan.exe tool may incorrectly report that the following versions of Windows are vulnerable :
  • Microsoft Windows 95
  • Microsoft Windows 98
  • Microsoft Windows 98 Second Edition
  • Microsoft Windows Millennium Edition
• The original version of the KB824146scan.exe tool (1.00.0249 ) cannot determine whether the 823980 (MS03-026) and the 824146 (MS03-039) security patches are installed on a Windows NT 4.0-based computer that has the RestrictAnonymous value set to 1 in the following registry key:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
  
  
  In this case, the KB824146scan.exe tool reports the following error status for the target computer: “cannot get workstation info: error 997 (0x000003E5).” To determine whether these computers have been patched, use version 1.00.0257 of the KB824146scan.exe, or manually inspect all Windows NT 4.0-based computers that have the RestrictAnonymous value turned on.
• You cannot use double-byte character set (DBCS) characters in the path for the input file, the output file, the log file, or the host computer when you use the KB824146scan.exe tool.
