I have a machine running Windows XP SP3 using IE7. When I go to ups.com, choose USA, and click the `login` button at the top of the page, the page hangs and never loads.

If I change the DNS to google's 8.8.8.8 the page loads.

All of the other machines (there are more than ten of them) using the same DNS that this computer used before switching to google are able to load the page just fine.

This makes me believe it's an issue with this computer and not DNS.

I checked this on machines running IE7 and IE8 and they were able to load the login page.

What is causing this problem?

Update: This began happening on more than one computer.
