Routine Description:

    This routine registers the LSA interface over any protocols that have
    been registered so far.  This routine is designed to be called on a
    domain controller after the DS has started since it already waits
    for the conditions necessary to register its RPC interface over TCP/IP.
    

    N.B. Should the DS ever not register of TCP/IP this mechanism will
    need to be updated.
    
    N.B. This routine is called from the thread pool call back mechanism.
    
Arguments:

    pVoid -- ignored.

Return Value:

    STATUS_SUCCESS

Routine Description:

    This function performs the initialization of the RPC server in the LSA

Arguments:

    None

Return Value:

    NTSTATUS - Standard Nt Result Code.

        All Result Code returned are from called routines.
