FIX: A COM+ application that is running on a Windows Server 2003-based computer stops responding and some work items that are queued in the MTA thread pool are not completed

When you run a COM+ application on a Windows Server 2003-based computer, some work items that are queued in the multithreaded apartment (MTA) thread pool are not completed. Additionally, the COM+ application stops responding until you restart the application. Additionally, during the time that the application is not responding, any DTC transactions that involve application components are aborted if the DTC transactions have not been committed.

This problem may occur when the number of the threads that can process the work items in the queue is zero.
