In the previous chapter, we discussed how network access is designed for a network infrastructure. We discussed internal and remote access and IP addressing options along with the security options an organization can use when trying to protect its resources.

Every computer that needs to communicate with other systems on the network, whether it is internal to the network or a remote system, needs to be able to determine the network addresses of other computers. Systems are uniquely named so that they are differentiated from every other system within the organization. These names are easy for us to understand, but operating systems use other means of identifying themselves in order to communicate.

In this chapter, we are going to discuss the available name resolution design options. Although DNS is the preferred name resolution method in a Windows Server 2003 network infrastructure, numerous organizations are still supporting applications or operating systems that utilize NetBIOS naming and need to have a NetBIOS name resolution method. In a Windows environment, WINS is used as the NetBIOS name resolution service.
