How does Wins resolve client names?
After some time after all WINS clients have received the WINS server to point to and have registered themselves, all clients can resolve all other client names through name resolution even across different networks. They perform this name resolution by querying the WINS server with NetBIOS name queries and responding to the requests with the correct IP addresses of the specific machines.
How does NetBIOS resolve names?
NetBT traditionally resolved names over a network by sending broadcast query messages over TCP/IP. NetBIOS most notably is non-routable. NetBIOS name resolution cannot happen over multiple networks. To remedy this, Microsoft developed a NetBIOS Naming Service or what most call WINS to resolve names across routed networks.

How to decommission Wins?
Be aware however that decommissioning WINS doesn't just mean pulling the plug on all your WINS servers. To properly decommission WINS in your environment, you will also need to remove any WINS settings in the TCP/IP configuration of clients and servers on your network. After all, you don't want any of the servers or clients on your network trying to contact a decommissioned WINS server to look up a NetBIOS name. For computers that use DHCP, you can simply remove any DHCP options configured for Option Type 44 WINS server (NetBIOS name server) see this link for more information. You will need to remove this option from server, scope, class and client-specific levels of your DHCP servers. And for clients or servers that have their TCP/IP settings manually configured, you'll need to remove the WINS configuration from these clients too.
What if you're in the process of upgrading your environment to use IPv6?
What if you're in the process of upgrading your environment to use IPv6? The latest versions of Microsoft Windows, both client and server, have IPv6 functionality not only enabled but preferred over I Pv4. WINS however only supports IPv4, so if you are planning on going IPv6-only then you should look into using DNS Global Names to provide NetBIOS name resolution for applications that use IPv6. DNS Global Names is described at http://technet.microsoft.com/en-us/library/cc816610 (v=WS.10).aspx and http://technet.microsoft.com/en-us/library/cc731744.aspx, and a good discussion of how it relates to WINS can be found at http://social.technet.microsoft.com/Forums/windowsserver/en-US/f7649be9-e702-42e5-9a2a-d78e78909a72/gnz?forum=winserverNIS.
