_narrow() will return a nil CORBA object if it is unable to match up the 
IOR with the type of the object you are requesting. You may want to turn 
up the debugging level on both sides to see what is being exchanged 
between client and server. Also try dumping the IOR and make sure it has 
a good host name the client machine can demonstrably use to find the 
server machine, independent of CORBA infrastructure.

I have used JacORB and omniORB with great success. The Sun ORB has 
always been less robust so you may want to consider switching.
