Microsoft® Windows® Server 2003 Domain Name System (DNS) provides efficient name resolution and interoperability with standards-based technologies. Deploying DNS in your client/server infrastructure enables resources on a TCP/IP network to locate other resources on the network by using host name-to-IP address resolution and IP address-to-host name resolution. The Active Directory® directory service requires DNS for locating network resources.
For more information about DNS, the Windows Server 2003 DNS Server service, and Windows Server 2003 DNS Client service, see the Networking Collection of the Windows Server 2003 Technical Reference (or see the Networking Collection on the Web at http://www.microsoft.com/reskit).
