Computer Fun

It appears we've had a bit of a networking problem here at The Manse.

Deb's computer has stopped communicating with the outside world and I've been delving into the problem. What I thought would be a job that I could quickly wrap up has turned into a three hour nightmare. Her machine now communicates with our router, but not beyond that. I've checked cables, rebooted her machine and the router, uninstalled and reinstalled drivers, and a host of other things, but nothing works. The only thing I haven't tried has been another NIC because I don't happen to have one handy (her machine has an integrated NIC on the motherboard).

Isn't owning computers fun?
