I recently had to repair Windows XP. I removed Service Pack 2, did the repair, and reloaded Service Pack 2 and all of the other updates that had been removed. The repair was successful, however Internet Explorer and Firefox would not connect to the Internet. I found that the only way to download Service Pack 2 was to go to Network Neighborhood and select Favorites. This allowed Internet Explorer to go to the Windows Update Page. Windows Explorer works fine in this mode until a new page in a new window is requested. Outlook, Outlook Express, Norton Anti-Virus, Quicken, and NoAdWare all access the Internet and work fine. I uninstalled Firefox and reinstalled it but that did not solve the problem. Thanks for your help.
