That didn't help me, but a new hard drive and a different OS confirm that this isn't a software problem, but a hardware one. Sometime in the week between when I first installed the machine and noticing the problem, my network card went south.

I'm working on getting the machine up with a new network card (the old one was onboard) and it might require me replacing the motherboard, but once I do, I can set you up with an account to poke around at things. thanks much, --=20 Jonathan "CowboyNeal" Pater | pater@slashdot.org http://cowboyneal.org/ | http://slashdot.org/ "I'm sure we can do this ourselves, Donny.
