5507 * processing has specified a server name that is not
5508 * "." and that the Server is remote and that the Share

5512 * The file system driver is faking the Bind-Ack response

5514 * encoded Pipe Service requests. For that we will use
5515 * the service's MSRPC module. However, unlike the SMB
5516 * server usage we must fake the MSRPC Bind exchange and
5517 * map the PipeName to an interface instead of using the
5518 * GUID specified in the MSRPC Bind request.
5520 * None of the requests that are being processed by the
5521 * service require authentication. As a result the userp
5522 * parameter will be ignored.
