I have a client who is having a very strange problem that I've never encountered before. The family has DSL and the connection is up and they can browse to *some* websites. For example, they can go to Google and do a search but when they try to follow the links none of them will go. They get the "Page could not be opened" message. (They are using IE not Netscape). I recently upgraded their machine from Windows Me to XP. When I left, it worked fine. A couple of days later they started having the problem. I tried to rule out any software related causes of this, even going so far as to remove a pop up blocker, which I didn't think was the culprit but I thought I should at least try. The firewall is also not enabled. Then, the woman suddenly tells me that they have another computer in the house and that it is behaving in exactly the same way. What in the world could be causing this? A faulty DSL modem would seem to cause no connection or intermittent connections but not always allow some pages to load and never allow other pages to load. This problem just started a few days ago and the only thing I know that has changed is the upgrade to XP. The other comptuer was untouched, and as I said, I didn't even know it was in the house. Can someone please help?
