Name Services in Windows 2000

DNS is the name service of Windows 2000. It is by design a highly reliable, hierarchical, distributed, and scalable database. Windows 2000 clients use DNS for name resolution and service location, including locating domain controllers for logon.

Downlevel clients (Windows NT 3.5 and 3.51, Windows NT 4.0, Windows 95, and Windows 98), however, rely on NetBIOS which can use NBNS (WINS), broadcast or flat LmHosts file. In particular, the NetBIOS name service is used for domain controller location.

Since DNS as implemented in Windows 2000 is Windows Internet Name Services (WINS)-aware, a combination of both DNS and WINS can be used in a mixed environment to achieve maximum efficiency in locating various network services and resources. Additionally, WINS in a legacy or mixed environment plays an important interoperability role while also preserving current investment.

Windows NT 4.0–based clients can register themselves in Windows 2000 WINS and Windows 2000–based clients can register in Windows NT 4.0 WINS.
