Internet Stopped Working with Windows Update KB951748
I have company laptop running XP w/ SP2. In the office I must use proxy to
access internet but from home I normally disable my proxy to reach the
internet (since some sites are blocked) but I must use VPN to reach sites on
company intranet. The other day I got an automatic Windows update (one update
consisted of KB951748) and when I got home that evening I noticed I could not
reach the internet unless I connect through my VPN and enable my proxy. I
normally connect wireless but I also could not connect using my wired network
connection. After checking the configuration on my nic and browser (Firefox
and IE7) settings I decided to investigate the updates that were done a few
days earlier. I noticed that the KB951748 update had an issue with Zone
Alarm. I don't use Zone Alarm but reading details how this update was
security update for DNS in XP I felt it may have affected me negatively also.
I uninstalled the KB951748 update and rebooted my laptop. Just like that I
now have internet again without having to use my VPN and proxy.
