SYMPTOMS
When a client computer logs off from a Terminal Services session, you receive a Stop error message on the terminal server that resembles the following:

Stop 0x000000AB (SESSION_HAS_VALID_POOL_ON_EXIT)

This problem occurs when the terminal server is running Microsoft Windows Server 2003 with Service Pack 1 (SP1) or with Service Pack 2 (SP2). When this problem occurs, other clients that are logged on to the same terminal server may also stop responding.

<div class="cause_section">

CAUSE
This problem occurs because the Ussy tag leaks session pool memory in the Win32k.sys file.
