Odd problem with Internet Explorer

[Powie]

Okay over the weekend I built a new server running Ubuntu 8. I had been running Fedora 7. Everything seemed fine until I went to work and tried to log in. I opened up IE 6, went to https://myserver.com was warned about my self signed cert as normal, clicked accept, and got a blank page. A few of my buddies at work also tried. Firefox on my friends laptop worked, as well as the IE7 he had updated to.

What is odd is everything worked fine at work last week on Fedora.

Anyone have any ideas? I deleted any "certificates" in Internet Explorers options menu, and still no luck.

Yes I know the real answer is stop using IE, or update it, but at work I don't have that option.

Thanks in advance for any ideas!
