SYMPTOMS
You may receive an access violation in the Lsass.exe service under low-memory conditions.



CAUSE
When memory for a local trust list is freed, some resources may not be successfully initialized under a NO_MEMORY condition. In this case, an access violation may occur in Lsass.exe during an attempt to free uninitialized fields in the trust list data structure.

Lsass.exe is the service responsible for all domain-related functions, such as user logon validation and user account management. If Lsass.exe does not complete successfully, all domain-related requests to the server are unsuccessful.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
