[omniORB] nameservice identified but failed to call server interface

[rmohan@ice-com.com]

Hi,

I am using call back example provided in omniORB3. Where

I am running
* nameservice on windows machine
* server process on Linux (successfully identified nameservice running on
windows)
* client process on windows machine where omninames is running.

The problem that I am getting is as follows
cb_client: server->one_time(call_back, client
Caught system exception COMM_FAILURE

But the server reference is not nil. What could be the problem.

Thanks,

Ram
