5461      * the service's MSRPC module.  However, unlike the SMB
5462      * server usage we must fake the MSRPC Bind exchange and
5463      * map the PipeName to an interface instead of using the
5464      * GUID specified in the MSRPC Bind request.

5466      * None of the requests that are being processed by the
5467      * service require authentication.  As a result the userp
5468      * parameter will be ignored.
5469      *
5470      * Although there are dozens of Pipe Services, the only
5471      * ones that we are implementing are WKSSVC and SRVSVC.
5472      * These support NetShareEnum, NetShareGetInfo,
5473      * NetServerGetInfo, and NetWorkstaGetInfo which are
5474      * commonly queried by NET VIEW, the Explorer Shell,
5475      * and the Common Control File dialog.
