If you plan on actually using samba on this machine, you'll need these, 
netbios-ns is the WINS name resolution so that you can access your machine by 
it's windows hostname, and the netbios-dgm is for data (if I remember 
correctly).

An option you may have is using samba or a wrapper (I'm not sure if 
tcpwrappers will handle udp) to limit permissions only to certain hosts.
