Routine Description:

    Registers the control handler with the dispatcher thread.  Then it
    performs all initialization including the starting of the RPC server.
    If any of the initialization fails, SpoolerStatusUpdate is called so that the
    status is updated and the thread is terminated.

Arguments:



Return Value:
