A DNS server maps hostnames to IP addresses for DNS clients. These clients query their assigned DNS servers when they need to resolve a hostname. A DNS zone stores the records for a specific namespace. A forward lookup zone map hostnames to IP addresses where as a reverse lookup zone maps IP addresses to hostnames.

DNS can be installed using different methods. You can install it from the Manage Your Server window or you can use the Add or Remove Program applet within the Control Panel. There no real requirements for installing DNS, other than the fact that you must be running Windows Server 2003 (or Windows 2000).
