Routine Description:

    This function performs the initialization of the RPC server in the LSA
    subsystem.  Clients such as the Local Security Manager on this or some
    other machine will then be able to call the LSA API that use RPC .

Arguments:

    None

Return Value:

    NTSTATUS - Standard Nt Result Code.

        All Result Code returned are from called routines.
