Updated: October 19, 2007

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

After you install the DNS Server service on new domain controllers, update the DNS delegation for the forest root domain on a DNS server that is authoritative for the parent zone.

To update the DNS delegation records for the additional domain controller

  1. Create a name server (NS) resource record in the parent zone. Use the left-most portion of the forest root domain name, and the full DNS name of the additional domain controller.

    forest_root_domain IN NS additional_domain_controller_name

  2. Create a host address (A) resource record in the parent zone. Use the full DNS name of the domain controller.

    additional_domain_controller_name IN A additional_domain_controller_ip_address

    For example, the DNS administrator for Trey Research created the following DNS resource records in the parent zone, treyresearch.net:

    • trccorp IN NS SEA-TRC-DC02.trccorp.treyresearch.net

    • SEA-TRC-DC02.trccorp.treyresearch.net IN A 172.16.16.3
