10.1.2.1 WINS in a Routed Environment
WINS consists of the following two components:
● The WINS server, which handles name queries and registrations.
● Client software, which registers computer names and queries for computer name
resolution.
Computers running
● Window NT
● Windows 95/98
● Windows for Workgroups 3.11 (with Microsoft TCP/IP-32)
● LAN Manager for DOS 2.2c
● Siemens Advanced Server for UNIX V3.51 (V3.5B10)
● Siemens Advanced Server for UNIX V4.0
can use WINS directly.
Non-WINS computers on the internetwork that are b-node compatible (as described in
RFCs 1001 and 1002) can access WINS through proxies (WINS-enabled computers that
listen to name-query broadcasts and then respond for names that are not on the local
subnet or are p-node computers).
To allow browsing across routers without WINS, the network administrator must ensure that
the users’ primary domain has Advanced Server, Windows NT Server, or Windows NT
Workstation computers on both sides of the router to act as master browsers. These
computers need correctly configured LMHOSTS
/ names.cfg files with entries for the domain
controllers across the subnet.
With WINS, such strategies are not necessary because the WINS servers and proxies
transparently provide the support necessary for browsing across routers where domains
span the routers.
The following illustration shows a small internetwork, with three local area networks
connected by a router. Two of the subnets include WINS name servers, which can be used
by clients on both subnets. WINS-enabled computers, including proxies, access the WINS
server directly, and the computers using broadcasts access the WINS server through
proxies. Proxies intercept the broadcast messages and send them directly to the WINS
server.
