How to connection share with Vista?

[TH3 H4NGMAN]

I used to do connection sharing between my Xbox 360 and my Windows XP PC, but then the XP machine died, so now I need to figure out how to do it in Vista. In XP, I would just check the box that said "enable connection sharing" and then plug in my cable and it worked. When I do that in Vista, it doesn't work. I've turned off all my firewalls that interfered on the XP machine like Windows Defender, but it sill doesn't work. I have the same firewalls as I used to, AVG 8 free. What am I doing wrong?
