i added secured netbios name registration (rfc1001/2.txt) which first
came out in 1.9.16alpha3.
this should allow a non-de-registered NetBIOS name to be claimed by
someone else if the current owner does not defend it (secured nbns must
check that the current owner still wants a name, if someone else attempts
to register it).
there may be something screwy going on, such that, by the third attempt,
relevant sections of log files at debug level 10
should help find out what's going in.
