WINS
The WINS service remains in place to support down-level clients. WINS filled the role of domain
and computer locator service for previous versions of Windows NT. Windows Server 2003 does
not require WINS in an environment without NetBIOS. However, WINS is always required in a
mixed environment where Windows Server 2003–based computers interoperate with other
systems, such as Windows NT 4.0, Windows 95, Windows 98, and Windows for Workgroups.
WINS Referral is the recommended way for Windows Server 2003 to address down-level
computers registered in WINS. Because Windows Server 2003 resolvers are optimized to use
DNS, they are much more efficient looking up down-level clients in a DNS database as opposed
to WINS database. To enable this kind of lookup, a WINS referral zone can be created in DNS
that points to the WINS database.
For example, the zone shown in the following dialog box does not perform any registrations or
updates; it refers DNS lookups to WINS.
