I have Norton Personal Firewall 2002 fully upgraded but sometimes when I'm visiting the antionline forum at http://www.antionline.com/index.php?action=forums and then clicking on a forum like Newbie Questions and Explorer is showing the "Page cannot be found"-error! I set NPF2002 to lowest security and privacy and thing but it still don't work!! When I disable the firewall everything is perfect. Someone having a soulution?
