This parameter allows you to assign a name for each node, or workstation, in the NetBIOS LAN environment. This nname is the basis for the actual NetBIOS names that will be registered for a NetBIOS protocol workstation. You must ensure that each node in the NetBIOS LAN environment has a unique nname.
Since the NetBIOS protocol establishes its communication connections using these NetBIOS names, the nname parameter must be set for both client and server nodes.
Client applications must know the nname of the server that contains the database to be accessed. The server's nname must be cataloged into the client node directories as the "server NNAME" parameter using the CATALOG NETBIOS NODE command, for example.
If nname at the server node changes to a new name, all clients accessing databases on that server must catalog this new name for the server.
