Any error messages?
My first thought would be a firewall blocking IE6 from connecting to the internet, but I doubt that is it if the pages seem to display then disappear. A firewall wouldn't even let that glimpse occur.
What is Windows 2000 Professional?
I have a friend using windows 2000 professional and internet explorer 6 for work at home . When you try to access any page on the internet using IE 6 , the page becomes blocked. The page might show for a second but becomes blocked .. Firefox works great but needs IE 6 for work ..AVG for anti-virus .Any help would be great
