Hmm, ipconfig /registerdns gets internet back?
Sounds to me like reseting TCP/IP does it so may I ask what DNS address you
are using in TCP/IP properties?

It should not be your ISP's DNS, in an Active Directory environment you must
use only your local DNS server. If your local DNS server cannot resolve
internet names use the DNS managment console to opem Forward Lookup Zones,
if you see a " . " Forward Lookup zone delete it! This will enable Root Hint
servers and allow you to configure a Forwarder to your ISP (DNS server
properties forwarder tab) after you have refreshed the DNS console.

Do _not_ use your ISP's DNS, in any position, on _any_ member of an AD
domain in TCP/IP properties.

An ipconfig /all from the DC and one of the clients will help diagnose this.

Did you check your DNS server for the Root zone?
Is "Disable recursion" checked on the Advanced tab?
Is the correct gateway configured on the NIC.

Please post your ipconfig /all for this server.
