You receive an error message and the computer automatically restarts when you change the password of a user account on a Windows Server 2003 R2-based domain controller that has Identity Management for UNIX installed

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: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.

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.
