Hmm. have you done a malware scan with something like Vipre Rescue and/or Malware Bytes and/or SpyBot S&D? I've seen something similar happen when a machine was infested with Malware.

Hi all, I wonder if anyone can help please? I have an issue on a clients XP SP3 machine in that they are able to successfully connect to the internet via an ADSL router, and ping hosts on the internet via hostname and IP address. However they are unable to browse web pages using any browser. I have tried all the tricks that I know to resolve this, but the issue still persists. The steps I have tried are: Ensured no proxy server settings are checked Ensured that DHCP and DNS are working correctly Ensured that ping responses are successful via both hostname and IP address Flushed the DNS cache Released and renewed IP via DHCP Tried multiple browsers (Firefox, IE, Google Chrome) Dumped the IE cache Installed all the latest patches Uninstalled expired anti-virus products (i understand that Norton has been a cause of this in the past, but n this case the AV is Avast Home Edition) Switched off any personal firewalls Unsuccessfully rolled back to a System restore point three months old Trouble-shot the NIC to ensure successful operation Reset the winsock catalog Removed the winsock and winsock2 registry entries Reinstalled the TCP stack Swearing at it I am poised with the XP install disk and ready to wipe the OS and rebuild the machine, but I thought I'd see if anyone on this list had resolved this issue before?
