XADM: Directory Service May Stop Unexpectedly During Exception Handling

• Microsoft Exchange Server, version 5.5

SYMPTOMS

The directory service may stop unexpectedly when it encounters an error leading to a particular exception handling routine that is to be invoked. If Dr. Watson is active as the default debugger, then a Dr. Watson log and a User.dmp (if configured to create a User.dmp) may be produced.

CAUSE

The exception handling routine causes the access violation when it attempts to de-reference a NULL pointer.

RESOLUTION

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

Q191014 XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack

STATUS

Microsoft has confirmed this to be a problem in Exchange Server version 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 2.
