Before you can configure DNS, you must first install the DNS service on the server. You can install DNS either during the initial installation of Windows Server 2003 or after the initial installation is complete. If you use the Active Directory Installation Wizard, you have the option to install and configure DNS when you configure the domain controller.
To install the DNS service on an existing installation of Windows Server 2003, follow these steps:
- Click Start, point to Control Panel, click Add or Remove Programs and then click Add/Remove Windows Components.
- In the Windows Component Wizard, click Networking Services (click the name, not the check box) in the Components list, and then click Details.
- In the Networking Services dialog box, click to select the Domain Name System (DNS) check box if it is not already selected, and then click OK.
- In the Windows Components Wizard, click Next to start Windows Server 2003 Setup. Insert the Windows Server 2003 installation CD-ROM into the CD drive or DVD drive if you are prompted to do so.Setup copies the DNS service and tool files to your computer.
- When Setup is complete, click Finish.
To install the DNS service during the initial installation of Windows Server 2003, Standard Edition or Windows Server 2003, Enterprise Edition, follow steps 2 and 3 when you are prompted to install and configure Windows components.
For a DNS server to function properly, the DNS server has to have a forward lookup zone that hosts the locator records for the DNS server’s local domain. A forward lookup zone contains information to resolve names in the DNS domain. You may want to also configure a reverse lookup zone that allows users to determine the name of a local resource based on its IP address. See How to Configure Windows 2003 DNS Servers
