Can't view any pages with IE7

[supesman]

I have a weird problem. I cant bring up any webpage in IE 7, get a page cannot be displayed. Worked fine yesterday. This computer has win xp and no firefox. I can ping www.yahoo.com so I doubt it's a DNS issue. Any ideas on what it can be?

Any firewalls blocking port 80?
