I was investigating this problem, when trying to play a 2 player game over LAN.

It would disconnect when I had a fresh WinXP install vs an actualized XP, Vista or Win7 PC.

After actualizing I can play two player games. But as others have noted before, a third player will get disconnected. With a pool of three PCs all running XP Home, each pair can play but not all three of them.

Does anyone know if the MSXML 4.0 sp3 solves the Problem for more than two players? Or what else must be done?
