I work the phones at an ISP. We’ve been getting lots of calls over the past couple of months or so where people are able to connect, but after 10 – 15 minutes they start getting "Page Cannot Be Displayed" errors when trying to access any web sites. They are still connected to the Internet and are still able to send and receive mail. I have had them go into DOS and ping various web sites and they get a reply (both by IP address & name). I have them try to go to the web site directly by the IP address that ping returns, and that doesn’t work either. I will even ping the web site from my PC and have them put in the numbers I get back and it still doesn’t work. I plug in the IP address on my PC and it works fine. They reboot their computers and are able to connect for another 10 – 15 minutes then the problem repeats. This happens whether they are connected through dialup or DSL. It doesn’t matter what browser they’re using, and they all are running Windows XP (so far) with all the updates installed. So far there have been 20 or 30 people with this problem.

I've asked and they have virus scan, all up to date. No firewalls are installed (most of the time, anyway) and I've tried turning off the Windows XP firewall also. I also had them install Spybot Search & Destroy and Ad-Aware and the systems come up clean

Has anyone else been experiencing this or have any suggestions? We’re all baffled here. Our techs assure me that it's nothing on our end, which makes sense to me because we have over 2000 clients who AREN'T calling in.

Thanks.
