SYMPTOMS
When a user logs off a Microsoft Windows Server 2003 Service Pack 1 (SP1)-based terminal server, the terminal server may stop responding (hang) for several seconds.

Note If many users log off at the same time, this behavior may be exacerbated. In this scenario, the unresponsiveness may last several seconds or several minutes. Additionally, the behavior may become more noticeable to users who are still logged on.



CAUSE
This problem occurs because of the way that Windows Server 2003 Service Pack 1 (SP1) cleans up user registry information. When a user logs off, there is a five-second delay before Windows Server 2003 SP1 flushes the user registry hive. If the terminal server experiences heavy registry activity, the cached registry information on the terminal server may increase significantly. For example, this behavior may occur when a program scans the user profile during the logoff process. When the terminal server experiences heavy registry activity, it takes Windows longer to flush the data.
