What version of IE?
Are you saying it won't display any web pages at all or just some?
What happened or what changes caused it not to work?
Have you tried another browser and did it work?
Did you uninstall and reinstall IE?
Are you using the default settings?

What firewall are you using? ARe you using more than one - maybe from windows and an antivirus program?
What anti-virus program?
Have you tried to turn off firewall and anti-virus program just briefly to see if pages will display?
