Routine Description:

    Starts the object resolver service.

Arguments:

    None

Return Value:

    None

Notes:   This function is a bit weak on cleanup code in case of errors.  This
         is because if this function fails for any reason, RPCSS will not 
         start.   Usually this function will never fail since 1) we always
         start at machine boot, when lots of memory is available; and 2) we 
         don't support stopping or restarting of RPCSS.
