Name resolution is the process of converting the friendly names you assign to computers into the IP addresses that TCP/IP systems need to communicate. The two types of names that Windows computers might have to resolve are DNS names and NetBIOS names. DNS is a hierarchical, distributed database of names and IP addresses that is stored on servers all over the Internet. A DNS name consists of a single host name plus a domain name that consists of two or more words, separated by periods. Individual users and organizations can lease second-level domain names, giving them the right to create any number of hosts and additional domain levels. Depending on the functions required by your network, a DNS server might require a registered IP address, a registered domain name, an Internet connection, or an Internet connection in combination with a registered IP address or registered domain name. Microsoft Windows versions prior to Windows 2000 use NetBIOS names to iden tify network computers. Windows supports a number of NetBIOS name resolution mechanisms, including WINS.

Once you have determined how your network will use the DNS, it is time to begin designing the DNS namespace for your network. The namespace design can include a host-naming pattern for all the computers on your network, as well as the more com plex naming of the network s domains and subdomains, both on the Internet and in Active Directory.
After this lesson, you will be able to
Create an effective DNS domain hierarchy Divide domain and host naming rules Create a namespace with internal and external domains
Estimated lesson time: 30 minutes
Using an Existing Namespace
If you are designing a new network from scratch, you are creating a new DNS namespace as well, which means that you don t have to work existing domains and hosts into your naming strategy. If the organization for which you are designing the network already has domain names in use, whether internal or external, or has a com puter naming strategy already in place, it is probably best to retain those elements and build your new DNS namespace around them. If the organization already has an Internet presence, they probably already have at least one registered domain name and the use of a DNS server to host the domain. You can continue using the existing the domain name, even expanding it to include internal subdomains. You can also continue using the existing DNS server, or migrate the DNS services to a new server on the network you are designing. If you change the DNS server, you must inform the domain registrar, so they can alter the IP addresses of the authoritative servers in the top-level domain records. The changes can take a few days to propagate throughout the Internet, so it is a good idea to have an overlap period during which both the old and new DNS servers are operational.
Upgrading NetBIOS to DNS
If you are upgrading a NetBIOS network to Windows Server 2003 and Active Directory, you already have an internal NetBIOS namespace, which you can migrate to DNS, gradually or immediately. For example, if you are currently using WINS for NetBIOS name resolution, you can configure Windows Server 2003 DNS servers to resolve the NetBIOS names by sending queries to your WINS serv ers. You can also continue to use your existing NetBIOS names by integrating them into your DNS namespace design.
