We have a servlet that sends a request over a socket to an application on another server. The client piece waits for a response.

One client is having trouble receiving a response (only some responses fail, but it is consistently the same responses). We wrote a test program to duplicate the issue. The problem is that they do not seem to get a response for this one scenario. Now if we put the test program on a different computer on their intranet, it then works. The "bad" servier is windows 2003, and the one that works is windows xp. In house we are not sure if we ever tested on a windows 2003.

If we shut down the server application, then the message is returned to the client when the server's side of the connection is terminated.

Should we be looking for firewall issues? Should we be looking for windows 2003 issues?

Try running ethereal(network packet captuerer from http://www.ethereal.com/ ) on both server and client and try to start transaction and see for packets traversed between server/client
