I have just replied to another of your posts and suggested you get a firewall. Now reading this post I see you have one. Sorry,
Instead of disabling ZoneAlarm, open it up, (double click the system tray icon), choose Program Control from the list on the left, and then select the Programs tab in the main window.
Scroll down to Internet Explorer, and see if you have green ticks, red crosses or blue question marks in the 5 boxes.
If you have red X's, then that is stopping IE from connection to the internet. Change those as necessary
I had a problem getting in IE today. I disabled Zone Alarm and now I got into IE. However, when I restore Zone Alarm, I cannot get into IE? I never had a problem with Zone Alarm until today?
