The Domain Name System is a directory of registered computer names and IP addresses that can be instantly located. Without proper design and administration of DNS, computers wouldn't be able to locate each other on the network, and applications like email and web browsing wouldn't be feasible. Administrators need this information to make their networks work. Windows 2000 DNS provides a technical overview to DNS, WINS, and how to design and administer them for optimal performance in a Windows 2000 environment.
