Still looking into it! I have a few things to check, and maybe it's them too. I haven't changed the network card out because I let my Wifes parents use it, but I just got it back last night, so I'll swap out the card today around 3PM EST -5GMT so please post your results after that time.
We'll figure out what this is, if I have to freaking build a new damn server.
(ack!)
