5510      * the service's MSRPC module.  However, unlike the SMB
5511      * server usage we must fake the MSRPC Bind exchange and
5512      * map the PipeName to an interface instead of using the
5513      * GUID specified in the MSRPC Bind request.

5515      * None of the requests that are being processed by the
