Role of WINS in the Network
Although NetBIOS and NetBIOS names can be used with network
protocols other than TCP/IP, WINS was designed specifically to support
NetBIOS over TCP/IP (NetBT). WINS is required for any environment in
which users access resources that have NetBIOS names. If you do not use
WINS in such a network, you cannot connect to a remote network resource
by using its NetBIOS name unless you use Lmhosts files, and you might be
unable to establish file and print sharing connections.
WINS Name Registration and Resolution
In a typical scenario, the following occurs:
In a typical scenario, the following occurs:-
ClientA, which uses NetBIOS and is a WINS client, sends a name
registration request to its configured primary WINS server (WINSA) when
it starts up and joins the network. WINSA adds ClientA's NetBIOS name
and IP address to the WINS database.
-
When ClientB needs to connect to ClientA by its name, it requests the IP address from the WINS server.
-
The WINS server locates the corresponding entry in its database and replies with ClientA's IP address.
Summary of WINS Benefits
WINS provides the following benefits over other NetBIOS name resolution methods:
-
WINS name resolution reduces NetBIOS name query broadcast traffic
because clients can query a WINS server directly instead of broadcasting
queries.
-
WINS enables the Computer Browser service to collect and distribute browse lists across IP routers.
-
The WINS dynamic name-to-address database supports NetBIOS name
registration and resolution in environments where DHCP-enabled clients
are configured for dynamic TCP/IP address allocation.
-
The WINS database also supports centralized management and replicates name-to-address mappings to other WINS servers.
-
WINS and DNS can be used in the same environment to provide combined name searches in both namespaces.
WINS and DNS
WINS and DNS are both name resolution services for TCP/IP
networks. While WINS resolves names in the NetBIOS namespace, DNS
resolves names in the DNS domain namespace. WINS primarily supports
clients that run older versions of Windows and applications that use
NetBIOS. Windows 2000, Windows XP, and Windows Server 2003 use DNS names
in addition to NetBIOS names. Environments that include some computers
that use NetBIOS names and other computers that use domain names must
include both WINS servers and DNS servers.
