IE7 error message: "The address is not valid"
Firefox error message: "Unable to connect"
I have a user who is suddenly unable to view websites after installing Internet Explorer 7 and some Windows Updates on Windows XP SP2. It only seems that the browser is affected (port 80?), as access is available to the rest of the network (files on server) and other programs that access the internet for information (Google Earth works fine, so does Windows Update).
Also, the results are the same when I test using either wireless or ethernet.
So far, I have uninstalled any recent updates to eliminate any potential causes and even installed FireFox to make sure that IE7 isn't the main culprit. Also, the run-of-the-mill troubleshooting methods, like disabling firewall and anti-virus, repairing network connections, etc, have been tried with no effect.
All searches thus far have been too erroneous to narrow down to a proper solution so any suggestions would be greatly appreciated.
