ICS internet access problem
in [Network and Web]

From: fred on 26 Apr 2008 19:01 A wierd one here ! Upgraded my WIN98 pc to XP and it connected to the internet fine via the cable modem. Reloaded several times to confirm all was ok then switched ICS on so that my other pc's could use the internet. This connection is via a second NIC feeding a 3COM 24 port switch. All other pc's - XP desktop, WIN 98 laptop and Win 2K laptop now connect to the internet ok, BUT, the main pc, ie the one which connects to the internet and through which all the others route, now will no longer connect to any web sites..... I can ping external ip addresses from the main pc and get a response ok, but trying to connect to any web site using I.Explorer or Firefox I get "can't find the server", email access attempts get a similar response. The win XP firewall is disabled and I get the same response with zonealarm disabled. THe other pc's work fine ! Seen a few people on the internet asking about the same problem but never any solutions. Any help/advice please as this is driving me mad............. Thanks.

It's hard to get the ICS to work with the free version of ZoneAlarm. On the main PC, lower the ZoneAlarm setting on the Internet connection from high to medium. If that doesn't help, un-install ZoneAlarm and enable the Windows Firewall. -- Best Wishes, Steve Winograd, MS-MVP (Windows Networking) Please post any reply as a follow-up message in the news group for everyone to see.

From: fred on 27 Apr 2008 03:48 Steve, Thanks ! that's done the trick. I had disabled zonealarm several times but that didn't cure the problem - I never thought of completely uninstalling it. Once again thankyou. ..............
