Windows Server 2008 uses the Domain Name System (DNS) as its primary method of name resolution. DNS enables computers to register and resolve DNS domain names. DNS defines the rules under which com- puters are named and how names are resolved to IP addresses. Windows Server 2008 also supports Windows Internet Naming Service (WINS), which is covered in detail in Chapter 25, “Implementing and Maintaining WINS.” WINS provides a similar service for NetBIOS names as DNS provides for DNS domain names. WINS maps NetBIOS names to IP addresses for hosts running NetBIOS over TCP/IP.Installing the DNS Server Service The way you install the DNS Server service depends on whether you plan to use DNS with the Active Directory or without Active Directory. After you make that decision, you can install DNS as necessary. Using DNS with Active Directory On a domain with Active Directory, DNS is required to install the first domain control- ler in a domain. Active Directory doesn’t necessarily require Windows DNS, however. Active Directory is designed to work with any DNS server that supports dynamic updates and Service Location (SRV) records. This means Active Directory can work with any DNS server running Berkeley Internet Name Domain (BIND) version 8.1.2 or later. If you have DNS servers that use BIND version 8.1.2 or later, you can use those servers. If you don’t already have BIND servers, you probably won’t want to set these up because there are many benefits to using the Microsoft DNS Server service. When you install the DNS Server service as part of the Active Directory installation process, you can use Active Directory–integrated zones and take advantage of the many replication and security benefits of Active Directory. Here, any server configured as a domain controller with DNS and using Active Directory–integrated zones is an Active Directory primary name server. 767 768 Chapter 24 Implementing and Managing DNS Here’s how installation of DNS on the first domain controller in a domain works: 1. You use the Domain Controller Promotion tool (Dcpromo.exe) to install the first domain controller. During the installation process, you are prompted to specify the Active Directory domain name, as shown in the following screen. This sets the DNS name for the domain as well. Note For more information about promoting domain controllers, see “Installing Active Direc- tory Domain Services” on page 1112. 2. When the Active Directory installation process begins, the Active Directory Domain Services Installation Wizard will check the current DNS configuration. If no authoritative DNS servers are available for the domain, the wizard selects DNS Server as an additional installation option, as shown in the following screen:Chapter 24 Installing the DNS Server Service 7693. In most cases, you’ll want to install DNS. If you install DNS, the Active Directory Domain Services Installation Wizard will install and then configure DNS. As the next screen shows, this means a forward lookup zone will be created for the domain. The forward lookup zone will have the Start of Authority (SOA), Name Server (NS), and host Address (A) records for the server you are working with. This designates it as the authoritative name server for the domain. If desired, you can also create reverse lookup zones to allow for IP address to host name lookups. DNS servers support IPv4 and IPv6 for reverse lookups. Chapter 244.
