Make sure both computers have the same version of the game. A patched game will not beable to communicate with an unpatched game. I was trying to get this game to work over a lan and after hours of scratching my head I finally came across that the games were of different versions (one was patched, the other was not). I ran the latest patch on each computer, and presto it just worked.
