hmm i donno ive never used windows server 2003 can u go to my network places and then go to network connections you need to change the tcp/ip settings.

Yeah, you can do all that. Its pretty much the same layout as XP. Should the DNS servers be set to 0.0.0.0 on my xbox if the dns server on my pc is set to 192.168.0.1? Is there anything else i can change?

copy the ip and dns stuff from ur evox.ini and it be cool.

Hmm, you mean the default settings when i install evox? I tried that, didn't work either.
The xbox ip was 192.168.1.200
netmask was 255.255.255.0
default gateway 192.168.1.1

and i changed my pc to be on the same network but it still didn't work. Maybe i should try installing xp?

maybe go for it.

check the ip again because u might of disabled static ip addresses so all it needs doing is updating

Changing the OS will not fix this problem. Huge majority of Xbox networking problems are addressing mistakes. I would start there.

Paul advised you to make the Xbox gateway the same address as listed for Xbox but is the PC and it's gateway set to the same address? It looks like you might be trying to use 2 different addresses for the PC.
