So I turn to you, all mighty pit.

I built a computer, had Linux on it for a bit, everything was all dandy. Ran an Ethernet cord between my Linux computer and our xp, which is connected to a 2wire router. With Linux, everything auto detected and set up internet and what not for me.

Today, I upgraded to x64 XP pro on my Linux system. I'm having a real hard time getting the network set up so I can have my home built computer access the internet. Ive ran the wizard, restarted several times. I'm out of ideas. Any help?
But at least it let me onto the internet and the network. With windows, it wont let me do either..
