Name Resolution in Subnetted Domains without WINS

If your Advanced Server domain does not have WINS, you can manually configure NetBIOS names in a cache, hostfile or database. For Microsoft clients and servers you must manually populate the WINS name server database, the DNS database, or the LMHOSTS file with the name and IP address of the Advanced Server/9000. For Advanced Server/9000 servers, you must manually populate the NetBIOS name caches with the names and IP addresses of the NT Server and Advanced Server/9000s. (There is no need to populate client names in the Advanced Server/9000 NetBIOS name cache because it supports from-name caching).

From-name caching is when NetBIOS caches the source name and IP address of datagrams sent from the local subnet or a different subnet. It is for datagrams sent to a unique name register by the server or datagrams sent from different subnets. It adds the sender NetBIOS name and IP address to the name cache with a life of 10 minutes. From-name caching is only applicable for unique client and server NetBIOS names not domain (group) names.

NetBIOS will multicast datagrams sent to a group name with multiple entries in the name cache.

These approaches enable the following features to work in a subnetted domain:
