I've had sort of similar problems w/ an old lap top I use in the cellar. I had no communication between the lap top and the ISP - I was IN, but nothing was being transmitted OR received?!
What I ended up doing was re-dialing into my ISP a few more times then it was fine?! No clue what was going on or if I had botched my Norton AV when I was changing the settings ..... lol.
You don't use earthlink do you? That is who I use - may be it was a net work issue?
I didn't do control alt delete to see what was going on there - I will next time if it happens again. May be a virus?
