You experience a memory leak or a long domain logon time in Windows Vista, Windows 7, Windows Server 2008 or Windows Server 2008 R2 after you deploy Group Policy preferences to the computer

Symptoms

This hotfix resolves the following issues.

Issue 1

Assume that you have a client computer in a domain environment. The computer is running one of the following operating systems:

  • Windows Vista

  • Windows 7

  • Windows Server 2008 R2

You deploy Group Policy preferences (GPP) to the client computer by using item-level targeting using security groups. In this situation, a user of the client computer experiences a long domain logon time. This issue becomes more noticeable if the domain controller is only reachable over a slow link.

Note If you use network monitoring tools to troubleshoot this issue, you can see many Lightweight Directory Access Protocol (LDAP) queries that are checking the object type of group members in the domain. These LDAP queries originate from the computers that received GPP through item-level targeting.

Issue 2

When you apply GPP by using item level targeting for security groups, local ports are leaked in an OPEN_WAIT state. After some time, the nonpaged pool is depleted and the computer stops responding.

Note To determine whether you are experiencing this issue, run the netstat -ano command at a command prompt to look for connections to port 389.

The netstat -ano command returns output that resembles the following:

TCP 172.22.244.52:49186 172.22.244.50:389 CLOSE_WAIT 968 TCP 172.22.244.52:49227 172.22.244.50:389 CLOSE_WAIT 968 TCP 172.22.244.52:49258 172.22.244.50:389 CLOSE_WAIT 968 TCP 172.22.244.52:49284 172.22.244.50:389 CLOSE_WAIT 968 TCP 172.22.244.52:49300 172.22.244.50:389 CLOSE_WAIT 968 TCP 172.22.244.52:49315 172.22.244.50:389 CLOSE_WAIT 968 TCP 172.22.244.52:49331 172.22.244.50:389 CLOSE_WAIT 968
If you run this command again after some time (or if you run the gpupdate /force command) you will notice that the number of open ports grows.

To temporarily work around this issue, restart the computer. This action resolves the problem temporarily as it will close the open ports.

Issue 2

When you apply GPP by using item level targeting for security groups, you notice the SVCHOST instance running the Group Policy Service is leaking virtual memory.

Cause

Issue 1

This issue occurs because item-level targeting uses recursive group membership queries to determine which groups the computer is a member of. The expected behavior of item-level targeting is to query the groups that the computer is a member of.

Issue 2

This issue occurs because the ports are not closed as expected.

Issue 3

Along with the leaked ports, the component also leaks memory in the LDAP library.

Prerequisites

To apply this hotfix, you must be running one of the following operating systems:

  • Windows Vista Service Pack 1 (SP1)

  • Windows Server 2008

  • Windows 7

  • Windows 7 Service Pack 1 (SP1)

  • Windows Server 2008 R2

  • Windows Server 2008 R2 Service Pack 1 (SP1)

Registry information

To use the hotfix in this package, you do not have to make any changes to the registry.

Restart requirement

You do not have to restart the computer after you apply this hotfix.

Hotfix replacement information

This hotfix does not replace a previously released hotfix.

The global version of this hotfix installs files that have the attributes that are listed in the following tables. The dates and the times for these files are listed in Coordinated Universal Time (UTC). The dates and the times for these files on your local computer are displayed in your local time together with your current daylight saving time (DST) bias. Additionally, the dates and the times may change when you perform certain operations on the files.

Windows Vista and Windows Server 2008 file information notesImportant Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows Vista" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

Important: If the hotfix is uninstalled on Windows Vista, the GP Preference Client Side Extension is removed from the System. In case the Hotfix should be de-installed, but a previous Version of GP Preferences should remain on the System, the previous hotfix needs to be re-installed on the affected systems.

  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.

    Version

    Product

    SR_Level

    Service branch

    1.
    18xxx

    Windows Vista and Windows Server 2008

    SP1

    GDR

  • GDR service branches contain only those fixes that are widely released to address widespread, extremely important issues. LDR service branches contain hotfixes in addition to widely released fixes.

  • Service Pack 1 is integrated into the release version of Windows Server 2008.

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 and for Windows Vista" section. MUM files and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
