SYMPTOMS
When you repeatedly shut down and restart a COM+ object, the server object may stop responding to new calls until you reboot.

For example, if you repeatedly call the IISRESET command, a Microsoft Active Server Pages (ASP) page finally returns a server error. This occurs because Microsoft Internet Information Services (IIS) can no longer create a new instance of an IIS out-of-process (pooled) application.

In addition, Event ID 10010 may be logged from DCOM in the event viewer. This event includes the following description:

The server  did not register with DCOM within the required timeout.



CAUSE
Remote Procedure Call Server Service (RPCSS) abandons a critical section when an internal exception occurs. Therefore, when you start to run the COM+ object, RPCSS (in Svchost.exe) creates Dllhost.exe and connects to it through RPC. However, Dllhost.exe cannot register CLSID because the deadlock occurs in RPCSS. This deadlock finally leads to the COM+ initialization failure.
