A Windows Server 2003-based terminal server that also runs Citrix MetaFrame Presentation Server may stop responding every few days, and you may receive a gray screen when you log on to the terminal server

SYMPTOMS
In a network environment, a Windows Server 2003-based terminal server that also runs Citrix MetaFrame Presentation Server may stop responding every few days. When this issue occurs, you may receive a gray screen when you log on to the terminal server. In this case, you have to restart the terminal server again to resolve this problem.

Note This problem occurs when Microsoft Forefront Client Security, Forefront Endpoint Protection, or other antivirus software is installed on the terminal server. After you uninstall this software, the problem is resolved.
CAUSE
This problem occurs because of a deadlock in the Rdbss.sys file.
