The Domain Name System (DNS) is the Active Directory locator in Windows 2000. Active Directory clients and client tools use DNS to locate domain controllers for administration and logon. You must have a DNS server installed and configured for Active Directory and the associated client software to function correctly. This article guides you through the required DNS configuration.
NetBIOS name resolution (WINS server, LMHOSTS file, or NetBIOS broadcast) is still required for earlier versions of Windows to resolve network resources on an Active Directory domain.
Microsoft recommends that you use Microsoft DNS Server as supplied with Windows 2000 Server as your DNS server. However, Microsoft DNS is not required.
The DNS server that you use:
Version 8.1.2 and later of BIND (a popular DNS server implementation) supports both the SRV RR and dynamic update. (Version 8.1.1 does support dynamic updates but it has flaws that were fixed in 8.1.2.) If you are using a version of BIND that does not support dynamic update, you need to manually add records to the DNS server.
Note: Microsoft Windows NT 4.0 Server DNS does not support the SRV record. Use DNS Server that is provided with Windows 2000 Server.
This server becomes a DNS server for your network. You can also promote it to the domain controller role at a later time.
In the first step, you assign this server a static Internet Protocol (IP) configuration. DNS servers should not use dynamically assigned IP addresses, because a dynamic change of address could cause clients to lose contact with the DNS server.
Note: If you receive a warning from the DNS Caching Resolver service, click OK to dismiss the warning. The caching resolver is trying to contact the DNS server, but you have not finished configuring the server.
Continue to the next step to install Microsoft DNS Service:
Next, after installing and configuring DNS, proceed to the next 2 steps:
Promote this server to the domain controller role by using the Dcpromo.exe utility.
After the server has been promoted to the domain controller role, the DNS server can use the Active Directory Storage Integration feature (this is the recommended path). Proceed to the next step if you want to use Active Directory Storage Integration for DNS.
Active Directory Integrated DNS uses the directory for the storage and replication of DNS zone databases. If you decide to use Active Directory Integrated DNS, DNS runs on one or more domain controllers and you do not need to set up a separate DNS replication topology.
