Under the Glassfish Admin page, check under Configuration -> ORB -> IIOP Listeners -> orb-listener-1, make sure network address is the dns name/ip address of the glassfish server you are trying to connect to. Probably restart glassfish at this point.
Then add the appserv-rt.jar, appserv-admin.jar and javaee.jar files to your standalone client classpath.
What I suspect is happening is it's using the default 0.0.0.0, which is why it isn't working as standalone on another machine, and why it does run the stand alone client on the same machine as the server.
