dns problem unable to resolve external websites including windows updates
I have a 2000 domain with a 2000 server and around 100 clients.The dns on the windows 2000 system is not configured and we normally use the isp's dns server's to browse the internet.
I just yesterday got in a new ibm server after installing the windows 2008 server i managed to add the 2008 server to the existing 2000 domain by pointing the dns of the 2008 server to the 2000 server in tcp4 in network connections ie:192.168.1.121
After rebooting i found that i have managed to copy the entire active directory tree but now after changing the dns back to the original isp's dns ie:202.149.208.30 and 202.149.208.31 in the tcp the server was unable to connect to the internet.
After browsing the ee site i found out to resolve this we need to create in the dnsmgmt as a dns forwarder but in the dnsmgmnt when i click on the server properties>forwarders i cannot change it as it is not avaliable as this is the root server.
now my question.
1.I cannot reinstall dns without removing active directory what to do in this senario as i will lose all the objects in the AD if it is reinstalled.
2.Can i rebuild the dns part without disturbing the existing active directory.
Thanks

Active Directory requires some degree of internal DNS. Whatever server is your AD Domain controller should have the forwarder references, everybody else should go to the DC for DNS.

I tried using the link at http://technet.microsoft.com/en-us/library/cc754941.aspx to change the forwarders name to the my isp's ip address ie:202.149.208.30 and 202.149.208.31 using the command tool
dnscmd <ServerName> /ResetForwarders <MasterIPaddress >
after reboot the server is not starting up
help!!!

The problem i have is that once i install AD by joining server 2008 in the 2000 domain the internet stops functioning.anyway reinstalling the server 2008 again and will repeat the steps to join server 2008 into the domain.

write2keith,
You do mean that internet is just not working on the new server right? or is not working on all clients & the old server?
