How do I...Install and configure a DNS server in Windows Server 2008?

Configure appropriate zones

A forward lookup zone is simply a way to resolve host names to IP addresses. A reverse lookup zone allows a DNS server to discover the DNS name of the host. Basically, it is the exact opposite of a forward lookup zone. A reverse lookup zone is not required, but it is easy to configure and will allow for your Windows 2008 Server to have full DNS functionality.
