SYMPTOMS
When Component Object Model (COM) communicates with remote computers through Distributed Component Object Model (DCOM), it does not release all cached information from RPC Endpoint Mapper (RPCSS).

If a client (COM) program on one computer connects to to several remote servers (COM), this behavior results into a large handle count for RPCSS.



CAUSE
This behavior is caused by a problem in the RPC run-time component.
