Well, the Mozila part isn't entirely true, but anyway, you'll see. I really don't understand this. Btw, I'm using WinXP pro. A while back, my IE wouldn't load the page: www.microsoft.com (the site can not be found...) Fine, the site must been down. Next day, same thing and ever since. The cure ? I only have to type microsoft.com without the www. Even now there are a few sites I can't access at all, www or not. (And I know they're working fine because I can access them from work) Weird. Then later, a few sites are acting the same way, so I have to manually edit my favorites shortcuts to remove the www. Now before you start telling me it's the DNS server of my ISP acting up, I asked a coworker if he had the same problem. Nada (He and I are on cable with the same company). Hmmm... maybe it's IE acting up then. It might be a IE registry key that is bad. Then come the mozilla part. I d/l mozilla, install it, and try to reach the adresses not working in IE. Nope, not working either. At that point, I'm confused. Last night I called the tech at my ISP just to ask him if they ever heard of that kind of problem. No, they haven't... he even asked his supervisor to make sure. The thing is I'm about to reformat and reinstall my XP this weekend, so whatever the problem is should go away. But I really would like an answer to this if it ever happens again. So, have any of you guys experienced this before ? Or any ideas what causes this and a way to "repair" this ? Thanx in advance.
