Port 80 Blocked, Windows XP

Hmm. silmilar issue here. DNS works fine, but all major IP stuff (FTP, HTTP, HTTPS seems blocked. I've just disabled the firewall by stopping and disabling the service and then rebooting, but still have the same problem. I have recently uninstalled Norton internet security which might be causing the problem. I'll report back with any further findings. BTW did you ever get to the bottom of your problem? JB
