ZoneAlarm users - one of the latest July MS Hotfixes breaks your web access...
10/7/08 5:02:04 PM

If you can read this you either ain't got ZoneAlarm, ain't got the problem yet or you've already fixed the problem...

Got home this arve and found the PC just didn't want to surf any more, and a short playtime of dicking around ended up finding the ZoneAlarm firewall (freebie version) just blocked all web traffic.

Oddly enough you can still ping to the outside world...

Quick bit of Mr Google found this directly off the ZoneAlarm home site:

Important notice to ZoneAlarm customers -
Installation of Microsoft Update KB951748 may result in loss of Internet connectivity


Basically Billy's HotFix screws up ALL ZoneAlarm firewall products.

The link above shows a temporary workaround but you'll need to temporarily unbreak the problem as follows:

Option 1: Move Internet Zone slider to Medium
- Navigate to the "ZoneAlarm Firewall" panel
- Click on the "Firewall" tab
- Move the "Internet Zone" slider to medium

Option 2: Uninstall the hotfix
- Click the "Start Menu"
- Click "Control Panel", or click "Settings" then "Control Panel"
- Click on "Add or Remove Programs"
- On the top of the add/remove programs dialog box, you should see a checkbox that says "show updates". Select this checkbox
- Scroll down until you see "Security update for Windows (KB951748)"
- Click "Remove" to uninstall the hotfix

Thence upgrade to the latest version 70.483.000 to put you back where it was all working again.

Wait, so you've removed a hotfix to get this to work? I think ZoneAlarm is at fault here.

Does anyone know what KB951748 does? Because Google is littered with ZoneAlarm. -_-

Probably Zonealam at fault, who knows/cares.

Note the word(s) "temporary..." in my OP - the actual Fix is to update your ZA to the latest version.

Or ditch it altogether, mebbe. Whatever floats your aquatic transporter

What I ended up doing was was enable the WinDoze firewall (ptooie!) , disable ZoneAlarm, d'l the newest version, uninstall ZoneAlarm, reboot, run CCleaner to scrub out the normal Registry clutter, install the new version of Zonealarm, reboot, fiddle my custom network setings and Voila! Robert's your Mother's Brother and I'm back to annoy you all...

KB951748 is supposed to fix a DNS vulnability I think.

Unless I'm mistaken it has to to with the issue described in this thread.
