FIX: A Component Services application package may stop responding in Host Integration Server 2004 on Windows Server 2003

A Component Services application package may stop responding if the following conditions are true:

�	The Transaction Integrator (TI) Windows Initiated Processing (WIP) COM object in Microsoft Host Integration Server 2004 is running on a computer that is running Microsoft Windows Server 2003.
�	The TI WIP COM object is installed in the same Component Services application package as the client program that is accessing the TI WIP COM object. Note The client program in this case is a custom DLL that is written to call methods that are exposed by the TI WIP COM object.

This problem occurs when the client program makes a CreateObject function call on the TI WIP COM object. The TI Runtime then makes a Windows API call that blocks the threads in the Component Services application package Dllhost.exe process. Because these threads are blocked, the Component Services application package stops responding.
