XADM: AV in Dsamain.exe When Expanding or Scrolling Through Objects

When you are expanding or scrolling through objects in the Exchange Administrator program, the Microsoft Exchange Directory Service generates an access violation (AV) and the service terminates.

One of the objects that is to be displayed to the screen in the Administrator user interface has a time attribute (When-Changed or When- Created) set to an invalid time (anytime before midnight, 1/1/1970).

To resolve this problem for versions 4.0 and 5.0, obtain the following version 4.0 post-SP5 hotfix.

To resolve this problem for version 5.5, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:
