On your Microsoft Windows 2000 Server-based computer or your Microsoft Windows Server 2003-based computer that is running Terminal Services, you may experience the following symptoms:

•	The server becomes slow and unresponsive. Eventually, you cannot establish new Terminal Services sessions.
•	If you use Task Manager to view the running processes, you may see that there are several orphaned Csrss.exe processes. There are no corresponding Terminal Services client sessions when you view the sessions in Terminal Services Manager.
•	You cannot stop the orphaned Csrss.exe processes to free server resources. Therefore, the Csrss.exe processes may continue to accumulate until you must restart the server to free memory and CPU resources.

If you apply the hotfix that is described in the Microsoft Knowledge Base article 827350, this may help reduce the number of Csrss.exe processes, but you still experience the problem.

The problem occurs because of a regression that was introduced in Windows 2000 Service Pack 3 (SP3). Windows 2000 SP3 includes a fix that introduces a temporary winstation object in the Csrss.exe process. This fix is described in the following Microsoft Knowledge Base article:If the temporary winstation objects are not released correctly, you may experience the symptoms that are described earlier in this article.

Technical support for x64-based versions of Microsoft Windows

If your hardware came with a Microsoft Windows x64 edition already installed, your hardware manufacturer provides technical support and assistance for the Windows x64 edition. In this case, your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation by using unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with a Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware. If you purchased a Windows x64 edition such as a Microsoft Windows Server 2003 x64 edition separately, contact Microsoft for technical support.

For product information about Microsoft Windows XP Professional x64 Edition, visit the following Microsoft Web site: For product information about x64-based versions of Microsoft Windows Server 2003, visit the following Microsoft Web site:
