Creating Subdomains

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

If you are deploying DNS on a large enterprise network, or if you expect your network to expand to include additional subnets and sites, consider distributing the management of portions of your DNS namespace to the administrators for the different subnets and sites in your network. To distribute the management of your DNS namespace, create subdomains of your initial DNS domain and delegate the authority for these subdomains to DNS servers located on different subnets or sites. In this way, you can create any number of separate and autonomous entities within a DNS namespace, each of which is authoritative for a portion of the overall namespace.
