xbox,pc broadband sharing problem

[nthfinity]

i finally got my xbox live hooked up, and running last night just to run into a strange problem.

when running xbox live, my computer freezes up... perhpas some goofy as hell microsoft protocol? it really doesnt make much sence since the ip sharing goes on with a dhcp server upstairs...

i was just wondering if anybody else has the same problem, or knows a fix. its quite annoying

other then that, running independanly runs great...
