FIX: Error code 0x800706BA may be generated when a client computer makes a request to a remote COM+ object

Symptoms

When a client computer that is running Microsoft Windows XP makes a request to a remote Microsoft COM+ object, the request may fail. Additionally, error code 0x800706BA may be generated.

Note Error code 0x800706BA indicates that the remote procedure call (RPC) server is unavailable.

Cause

This problem occurs when the client computer that is running Windows XP releases the remote COM+ object. Approximately 20 seconds to 30 seconds after the client computer releases the remote COM+ object, the RPC ports that were used by DCOM on the server are closed. If the network is disconnected immediately after the client computer releases the remote COM+ object, the RPC ports that were used by DCOM on the server remain open for several hours. This can lead to port exhaustion. Future requests from the client computer to the remote COM+ object fail.
