I have a customer’s computer that suddenly can't connect to any internet or intranet site using any browser.
I have scanned the computer for viruses, but no viruses have been found.
The computer also can't browse any intranet or internet website using Google Chrome, Mozilla, or Safari.
I have checked the hosts and lmhosts file and no entries exist.
I have completely uninstalled Internet Explorer 8 have rebooted and then have uninstalled Internet Explorer, rebooted and then reinstalled Internet Explorer. However, the computer still can open any internet or intranet sites.
Furthermore, the DHCP IP address information is correct and no other computers at this site are having any problems.
The computer can do all other network functions, such as sending and receiving email, printing, and browsing to network serve shares.
The computer is running Windows XP SP3.
What do I need to do to fix this?
