Updated: October 15, 2008

Applies To: Windows Server 2008, Windows Server 2008 R2

If you change the IP address of a domain controller that is a Domain Name System (DNS) server, if the server is designated as a forwarder for another DNS server you must update the IP address in the forwarder name server (NS) record. You can use this procedure to update the IP address of a forwarder for a domain controller that is also a DNS server.

Membership in Domain Admins, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).

  1. Open the DNS snap-in: On the Start menu, point to Administrative Tools, and then click DNS.

  2. In the console tree, if you are connected to the DNS server that uses the forwarder whose IP address you want to change, go to step 4. If you are not connected to the DNS server that uses the forwarder, right-click DNS and then click Connect to DNS Server.

  3. Click The following computer, type the name of the DNS server that uses the forwarder, and then click OK.

  4. In the console tree, click the node for the DNS server that uses the forwarder whose IP address has changed.

  5. In the details pane, double-click Forwarders.

  6. In the IP Address list, click the address that you want to change, and then click Edit.

  7. In the IP Address list, click the address, and then type changes as necessary.

  8. Click OK twice.
