DNS Installation and Configuration

When you install the first domain controller in a domain, if DNS is not available on the network, you can elect to have DNS installed and configured automatically during the installation of Active Directory.

The Active Directory Installation Wizard asks whether to install and configure the DNS service automatically if either one of the following conditions is true:

• You are creating a new forest, and the Active Directory Installation Wizard does not find any DNS servers that are running on the network
• You are creating a new domain, and dynamic update is not available.

You also can install the DNS Manager snap-in and use the tool to configure DNS either before or after Active Directory is installed. For more information about automatic DNS configuration and DNS requirements for Active Directory, see "Windows 2000 DNS" in the TCP/IP Core Networking Guide.
