Routine Description:

  This is the RPC server entry point, it returns the version

Arguments:

   hBinding    Not used.


Return Value:

   Return the version number, with the major version in the high byte and
   the minor version number in the low byte.

Routine Description:

Routine Description:

    This routine is currently not an rpc routine, it is called directly

Return Value:

    Return CR_SUCCESS if the function succeeds, otherwise it returns one
