Setting Up DNS for Active Directory
Basic Concepts of DNS and Active Directory
For DNS to function as a location service for Active Directory, you must have a DNS server to host the locator records (A, SRV, and CNAME). For more information about the locator, see "Active Directory Logical Structure" in the Microsoft ® Windows ® 2000 Server Resource Kit Distributed Systems Guide .
You can configure your Windows 2000 DNS server automatically by using the Active Directory Installation wizard, which is a wizard provided in Windows 2000 that installs and configures Active Directory. The Active Directory Installation wizard can perform all the installation and configuration necessary for DNS, and the Netlogon service adds the necessary locator records. For more information about the Active Directory Installation wizard, see "Using the Active Directory Installation Wizard" later in this chapter.
Unless you are using a DNS server other than Windows 2000 or you want to perform special configuration, you do not need to manually configure DNS to support Active Directory. However, if you want to set up a configuration other than the default configuration that the Active Directory Installation wizard sets up, you can manually configure DNS. In Windows 2000, you can configure DNS by using the DNS console. For information about the DNS console and when you might want or need to use it, see "Using the Configure DNS Server Wizard" later in this chapter.
If you are using a third-party DNS server, you must also perform manual configuration. For information about issues related to configuring DNS when you are using a third-party DNS server, see "Configuring Non-Windows 2000 DNS Servers to Support Active Directory" later in this chapter.
