Sorry for the delay in responding to you.

The Name Service, as with any CORBA server, uses Acceptors when accepting
connections.  It is during the creation of these Acceptors that the local
address is retrieved and stored for use with some internal Orbacus
functions.  Unfortunately, the particular Java call that is used to
retrieve the local address requires that the machine be configured
properly.  If not, and Java is unable to resolve the local address of the
machine, the result is what you are seeing, an UnknownHostException.

I don't think there would be anyway to pass the IP address of the machine
on the command line and have this work.  The problem here is that the JVM 
has to be able to resolve this address, since the call that is creating 
the exception is a Java InetAddress method call.  Passing the IP address 
to the Name Service would still not provide this address to the JVM.  I 
think the only way to resolve this is to ensure that you have a completely 
configured system.

Darren
