Server 2003 x64 SP2 Internet Explorer Problem

[Guest Viper]

We have a windows 2003 x64 enterprise edition server and I installed

Service Pack 2 from the windows update site. After the install I

rebooted and now the server can't get to Windows update or any other

website. I can still remote desktop to the server and i've tried

installing IE7 x64 edition but to no avail. DNS is working but when i

try to go to a website there is a syn_sent message listed in 'netstat -

a' but never a reply.

The windows firewall service isn't on and i've run out of things to

check. If you have any ideas please let me know.
