SYMPTOMS

When you log off from a Terminal Services session on a Microsoft Windows Server 2003 Service Pack 1 (SP1)-based Terminal Server, you may receive the following error message:
Stop 0x000000ab

CAUSE

This problem may occur if a driver has Session Pool Memory allocations that are not de-allocated or freed when a user logs off. The bug check 0xAB error is caused by a session driver that does not free its pool allocations before a session unload. This indicates that there is a bug in the Win32k.sys file, in the Stmfd.dll file, in the Rdpdd.dll file, or in a video driver.

For more information about the bug check 0xAB error, see the "More Information" section.
