SYMPTOMS
On a Microsoft Windows Server 2003 R2-based domain controller, you receive the following error message when you use Active Directory Users and Computers to change the password of a user account:

The system is shutting down. Please save all work in progress and log off. Any unsaved changes will be lost. This shutdown was initiated by NT AUTHORITY\SYSTEM.

Time before shutdown: 00:00:30

The system process ' \system32\lsass.exe' terminated unexpectedly with status code. The system will now shut down and restart.

Then, the computer automatically restarts.

This problem occurs if the following conditions are true:
 * The Identity Management for UNIX component is installed on the domain controller.
 * UNIX attributes are enabled in the user account whose password was changed.
 * Password synchronization is enabled between the Windows domain and a UNIX system.
 * Password synchronization is configured to use Message Digest 5 (MD5) as the encryption scheme.



CAUSE
This problem occurs because the password synchronization module incorrectly deallocates a resource. In this situation, an access violation causes the Lsass.exe process to stop unexpectedly.
