SUMMARY

This article describes methods that you can use to configure Domain Name System (DNS) if queries that are directed to the Internet are not resolved correctly, but local intranet name resolution functions correctly.

The Cache.dns file that stores root hints on your Windows Server 2003-based computer may be missing or damaged. You can manually add root hints by using the DNS snap-in, replace the Cache.dns file on your hard disk with the backup Cache.dns file or replace it with the original version of the Cache.dns file from the Windows Server 2003 CD.

To update root hints by using the DNS snap-in

To update root hints:

To manually add root hints on a Windows Server 2003-based DNS server that is not configured as a domain controller:
  1. Click Start, point to Administrative Tools, and then click DNS.
  2. In the right pane, right-click ServerName, where ServerName is the name of the server, and then click Properties
  3. Click the Root Hints tab, and then click Add.
  4. Specify the fully qualified domain name (FQDN) and the IP address of the root server that you want to add, and then click OK.
