Re: KB951748/Zone Alarm - Loss of connectivity

Have you tried rebuilding the winsock from a Command Prompt with ZA *completely* disabled and the native XP firewall enabled or, just disconnect from the net while doing the following ?

Start > Run > type in

cmd
Click OK or press Enter

At the Command Prompt, type in the below and press Enter after *each* command

netsh winsock reset
exit

Restart the system and see if connectivity is restored.
If no joy suggest you start a *free* support case with MS:

For home users, no-charge support is available by calling 1-866-PCSAFETY in the United States and Canada or by contacting your local Microsoft subsidiary. For more information about how to contact your local Microsoft subsidiary for support issues with security updates, visit the Microsoft International Support Web site:
http://support.microsoft.com/common/international.aspx?rdpath=4 North American customers can also obtain instant access to unlimited no-charge e-mail support or to unlimited individual chat support by visiting the following Microsoft Web site:
http://support.microsoft.com/oas/default.aspx?&prid=7552

Or, not. The decision is entirely yours. As is the decision to install Zone Alarm and continue using it when other free alternatives are available that are not toxic to the OS. Here's one:

For those experiencing a loss of internet connectivity after installing KB951748 with Zone Alarm installed as the firewall, here's the fix by a Zone Alarm moderator:
http://forum.zonelabs.org/zonelabs/board/message?board.id=cfg&message.id=52727


If the windows update changed the usual needed files for networking/internet, then the ZA will not see
the changes and continue to use the previously known files and ignore the newer files. Even though the
file names and locations are still the same from before, now the file size and checksums no longer match.

To solve this, just reset the ZA database and the ZA will be "fresh" as when it was first installed:

# Boot your computer into the Safe Mode
# Navigate to the c:\windows\internet logs folder
# Delete the backup.rdb, iamdb.rdb, *.ldb and the tvDebug files in the folder
# Clean the Recycle Bin
# Reboot into the normal mode
# ZA will be just like new with no previous settings or data


Once this is finished, reboot back into the normal mode and in the new network found windows, set the
new network to Trusted.
Then do this to ensure the ZA is setup properly:

Make sure your DNS and DHCP server IP's are in your Firewall's Trusted zone. Finding DNS and DCHP servers, etc

1. Go to Run and type in command and hit 'ok', and in the command then type in ipconfig /all then press the enter key. In the returned data list will be a line DNS and DHCP Servers with the IP address
(s) listed out to the side. Make sure there is a space between the ipconfig and the /all, and the font is the same (no capitals).
2. In ZA on your machine on the Firewall, open the Zones tab, click Add and then select IP Address. Make sure the Zone is set to Trusted. Add the DNS IP(s) .
3. Click OK and Apply. Then do the same for the DHCP server.
4. The localhost (127.0.0.1) must be listed as Trusted.
5. The Generic Host Process (svchost.exe) as seen in the Zone Alarm's Program's list must have server
rights for the Trusted Zone.
Plus it must have both Trusted and Internet Access.

Oldsod.
