Just a pedanticism...  Clients do not "authenticate" to an NBNS (WINS). 
WINS simply accepts any registrations that reach it and are not in

If the names begin with the computername, then they are unique names (not 
group names) and have the following meanings:

00 - Client service     (aka. the machine name.  Only available if the client
                        services are running.)
03 - Messenger service  (Windows pop-up messages.)
20 - Server service     (File sharing.  The server service makes it possible
                        for you to offer shares.)
