internet connection problems

[jlexen]

A couple days ago, after I started up my computer, I found that I couldn't use the internet. It seemed to know that I had an internet connection but I got the "The page cannot be displayed" message, and I can't sign into msn messenger. I tried using the same modem connection on another computer and it worked fine, but it still doesn't work on the first one.
I'm using Windows XP...I think a Dell 8400 or something like that. And I know I should supply more info about the computer, but I don't know what.

I know this sounds simple, but did u unplug it from the wall(power cord) and then plug it back in?  that works sometimes.  give that a shot, and then we can wrok from there.

tried it and no affect. I've also restarted my computer many times.

Do you use Zone Alarm?

[jlexen]

Wow, I shutdown zonealarm, and I could connect to the interent. When I turned it back on, I no longer could. Now we're getting somewhere.

I turned off the firewall on zonealarm and the internet will work. I guess I'll just use the windows firewall for now on...
thanks you guys
