help with front page 2003

Have a site published with an older version of FP. Bought a new computer with FP 2003. I successfully reverse published to get the remote site on my local drive. It worked fine for a couple weeks but now I'm having issues.

Every time I click "publish" it asks me to define the remote site properties. That's fine, but when I click "OK" it says "unable to access example.com because its..." blah, blah. It goes on to suggest that it might be a proxy setting or something.

Now, what's really odd is that if I log out of WinXP and log in as my wife, it publishes fine. I know its some setting that got changed somehow, but I double checked to see that all the settings are the same in mine and my wife's side of XP.

I tried disabling Norton Anti Virus, resetting LAN/proxy settings, but I'm missing something. I also tried repairing FP 2003 with the CD.
