Adding SP2 to your 2003 server, lost Internet access !

[ihatespam]

I have a situation that is known to many users, I have 4 2003 servers that were using SP1, once SP2 was installed they lost Internet access, they can even ping the sites by name and the ping comes back ok, but the only way I have found to regain access is to un-install the SP2, now for company policies I need to have SP2 installed, any ideas? Seems like this has been happening on many computers, different operating systems (like XP) with SP2 added, and to many customers all over but I can't find a fix, any help will be greatly appreciated.

I know there is a patch or fix for XP but I can't find one that will install in 2003.

If you make the following registry changes and reboot, does networking for SP2 start working again?
