I have two computers that were once both running Windows 95. By using an ethernet cable and adjusting the network settings, I was able to link them together so that two people could deathmatch, etc. One computer died, so I purchased another that runs Windows XP. I can link them together to share files and such, but I can't get a linked game of Doom going anymore. Does anyone know if it is possible to link a game between different OS's and if so, what settings are needed to make it work?
