How to run Corba on different computers via lan

Resently I learned how to run CORBA app on single PC by this video http://www.youtube.com/watch?v=BpefT4giUoU I have done the same and everything worked well on single pc. But I need to run corba app on two PC's via lan and I don't know how to do it. Maby some config of of client ORBD? I tried to run orbd and server on one PC with -ORBInitialPort and ORBInitialHost params and run client on different PC with ORBInitialPort and ORBInitialHost from remote ORBD, but it doesn't helped
