How To Remove the Root Zone (Dot Zone)

Summary

When you install DNS on a Windows 2000 server that does not have a connection to the Internet, the zone for the domain is created and a root zone, also known as a dot zone, is also created. This root zone may prevent access to the Internet for DNS and for clients of the DNS. If there is a root zone, there are no other zones other than those that are listed with DNS, and you cannot configure forwarders or root hint servers. For these reasons, you may have to remove the root zone.
