SYMPTOMS

When a Message Queuing component that uses the EnableNotification call is run under COM+, the thread in which the object lives is destroyed, and the object is released with the connection severed prematurely. The same component runs fine in an MTS environment.

CAUSE

Message Queuing uses an unregistered Windows message for EnableNotification. This message is intercepted, and COM+ deactivates the thread prematurely.

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:
