Why i am unable to bring up any web site(shows "IE can't display this page") using IE

I am unable to bring up any web site using IE. Firefox works fine. I have been working with Firefox so far. But I have to use some sites which only support IE. Any help in diagnosing and fixing this will be much appreciated.

Check the proxy settings in IE, perhaps you have something in there. Or if you need proxy settings, perhaps they are missing

Tools-%26gt;Internet Options-%26gt;Connections-%26gt;Lan Settings

Forget about IE. It is problematic. Use firefox since you say it works fine.
in firefox go to tools%26gt;options%26gt;advanced%26gt;network%26gt;settings and see the settings. Next in IE go to tools%26gt;internet options%26gt;connections%26gt;lan settings and make the settings same as u observe in ur firefox(as detailed earlier)
