I have been trying to play multiplayer game with Age of Empires. I am running XP on one machine and Win98 on the other with a microsoft router and firewall between the machines. I have tried everything I can, even shutting down the firewall but I cannot play between the two machines. The XP creates the game, the Win 98 sees the game but when you click on join, it display unable to join game. When the Win98 creates the game, the XP machine does not even see it. Everything else on the network works just fine. Any suggestions.

Make sure your router is configured correctly. Before you even go into the game try pinging the router's IP on both pc's and see if it pings back. It sounds like the problem is with your router... it took me a while before i got games to work w/ mine

Yea we had the same proble, we solved it by setting up the port config on your router. Also you could host the game and make ppl connnect to you router IP not your computer IP.
