The Provisioning Engine COM+ component stops responding in Hosted Messaging and Collaboration 4.0

Consider the following scenario. In Microsoft Hosted Messaging and Collaboration 4.0, you submit a request to a Microsoft Provisioning Server (MPS) engine that is stopped. When you restart the server, the MPS COM+ component stops responding. In this scenario, errors may occur when requests are submitted. The server may have to be restarted so that the MPS engine can work.

This problem occurs because of an interoperability issue between the COM+ subsystem and the OLEAUT32.dll file when the MPS engine COM+ component starts.
