>Yes, it's been like that for a few years now

A few years! You never saw a Universal Thread image since all that time? What about the toolbar at the top here? Do you see those images? Do you see images from the Universal Thread Magazine and Level Extreme .NET Magazine site?

>No, I've chopped and changed the settings over the years

There could be an unnecessary amount of security in place.

>I said AFAIK. There is Norton on the server and whatever firewall teh administrator has set up - I don't get involved with that. I should point out that I get the same "problem" on my home PC, where I have AVG and ZoneAlarm running, BUT, it was the same when I had Norton and no firewall. BTW, I do have a similar colour for Windows background but it's unlikely that my home PC settings are configured the same as my work's.

Once you will be at home tonight, could you disabled temporary those software and try to access the site?
