Well, for what it's worth, you've done a great job. As I read
your note, several times I started to think "oh, he should try..."
after which your next sentence told me that's exactly what you
had done.
I tend to concurr with your statement about the LAN card being
fried. It's unusual, but it happens. Fortunately they're cheap,
and a replacement could save you a lot of time & trouble.
The only other things that come to mind are the standard virus/spyware
thing, which I would guess you already are scanning for, and running
the system file checker. Some software - spyware mostly - has a
tendency to muck about with the network underpinnings when it shouldn't,
and there's a remote possibility that could cause this kind of behaviour.
Good luck!
Thanks for asking,
Leo
