KB2523459

Consider the following scenario:

  • You have a computer that is running Windows Vista or Windows Server 2008.
  • You uninstall or upgrade a program that is installed on the computer.
  • You perform a system state backup operation by using a Volume Shadow Copy Service-based (VSS-based) backup utility.
  • For example, you perform a system state backup by using IBM Tivoli Storage Manager (TSM).

In this scenario, the system state backup operation fails.

Note: If the backup utility adds logging or events when this issue occurs, the logging or events indicate that some system state files are missing.

KB2523134

Consider the following scenario:

  • You have a resource that is shared with several threads in Windows Vista or in Windows Server 2008.
  • You control threads to access the resource by using a named mutex object.

In this scenario, you may encounter the following issues:

  • Applications that use mutex stop responding.
  • The shared resource is corrupted.

Notes:
This issue may occur if the following conditions are true:

  • A named mutex object is opened and closed repeatedly.
  • The named mutex object has the same name every time that it is opened.

KB2535094

A computer that is running Windows Vista or Windows Server 2008 stops responding when it uses the Server Message Block Version 2 (SMB2) protocol to lock or unlock files on a network.

If you enable the special pool feature on the computer, you receive a Stop error message that resembles the following:

STOP: 0x000000D5 ( Parameter1 , Parameter2 , Parameter3 , Parameter4 )
DRIVER_PAGE_FAULT_IN_FREED_SPECIAL_POOL

Notes:

  • The parameters in this Stop error message vary, depending on the configuration of the computer.
  • Not all “0x000000D5” Stop errors are caused by this issue.

KB2553549

On a computer that is running Windows Vista or Windows Server 2008, all the TCP/IP ports that are in a TIME_WAIT status are not closed after 497 days from system startup. Therefore, TCP/IP ports may be exhausted, and new TCP/IP sessions may not be created.

Note: Some network-related operations to this computer may be affected by this issue. For example, you try to use some remote administration tools to manage a Windows Server 2008-based domain controller that has been running for more than 497 days. In this example, the remote administration tools cannot connect to the domain controller.

KB2532159

Consider the following scenario:

  • You install the Client for NFS component on a computer that is running Windows Vista, Windows Server 2008, Windows 7, or Windows Server 2008 R2.
  • You try to access some Network File System (NFS) shares on a server that has the READDIRPLUS remote procedure call (RPC) feature disabled.

In this scenario, the application that accesses the shared folders may stop responding.

KB2549268

In Windows Vista or in Windows Server 2008, Simple Network Management Protocol (SNMP) threads might not time out correctly. Therefore, the thread that polls an SNMP agent to call SNMP Management APIs may stop responding.

KB2545479

Consider the following scenario:

  • You run an application that is based on Microsoft Component Services (COM+) on a computer that is running one of the following Windows operating systems:
    • Windows Vista
    • Windows Server 2008
    • Windows 7
    • Windows Server 2008 R2
  • The application relies on some COM+ components that are registered as single-threaded.

Note: The threading-model property of the components is set to Single Thread Apartment (STA).

In this scenario, you may encounter the following two issues:

  • A memory leak occurs in the COM+ application. Therefore, the application stops responding.
  • Calls from clients to the COM+ components are placed in a waiting status. Therefore, client requests take a long time to execute.

KB2537589

When you run an application or service that accesses a remote Server Message Block (SMB)/Common Internet File System (CIFS) server, the number of CIFS sessions keeps increasing.

This issue occurs on a computer that is running one of the following operating systems:

  • Windows Vista
  • Windows Server 2008

When the resources are exhausted, the remote SMB/CIFS server does not respond to client requests.

KB2548554

You use FTP.exe to manipulate files over FTP on a computer that is running Windows Vista or Windows Server 2008. When you try to redirect the FTP output to a file, nothing is redirected.

For example, you run the following command to redirect the FTP output to a file:

ftp -i -s:ftpput.txt > result.txt

When you open the output file, you see content that resembles the following text:

open 10.1.1.11
220 FTP Server Version 2.0
331 User name ok, need password
230 User logged in
put [Path\filename]
200 PORT command successful.
150 File status OK ; about to open data connection
226 Closing data connection; File transfer successful.
0.190.09bye ******
221 Service closing control connection

In this redirected content, the FTP message is missing in the “0.190.09bye ******” line.

KB2548491

Assume that you dial a Secure Socket Tunneling Protocol (SSTP) connection to an external SSTP server from a computer that is running Windows Vista or Windows Server 2008 in an environment that has forward proxy configured. In this situation, the connection is unsuccessful. Additionally, you receive an 11004 error:

Host not found
