Hi, Ive just set up our home network. Both PC's are running WinXP SP2 with a crossover cable between them. Computer A is sharing an ADSL internet connection and B connects via A. I can share files between the two computers, the internet access works etc. But i cant use NET SEND USER message or access a game server hosted by either computer. Anybody have any idea why? ive checked over firewalls etc. I can also ping the other computer using both IP address and Username. Thanks Andrew
