Recently I had a client who could not get on the internet. After a quick check I found that Zone Alarm was preventing the computer from connecting to the internet. I recommended that he uses windows firewall and that he remove the Zonealarm program. It appears that on Tuesday the 8th Microsoft released a patch that took down internet access for anyone who was using Zonealarm. Specifically patch KB951748 update for Windows XP.
Zone Alarm (ZA) recommends using their latest patch which can be found at Zone Alarm patch. As stated before I don’t recommend using ZA unless you have no router or any other firewall. If you have XP you should just the firewall that’s built into XP.
If you don’t have access to the internet to get the patch here are a few things you can do:
· Adjust the Internet Zone security slider to Medium
· Uninstall KB951748
· Add your DNS servers to the Trusted Zone
Software affected includes:
