"insufficient context" [good grief, what a geeky way to say help, i can't
right, this is the "log in two users simultaneously, log them both out
and the second one hangs w95" problem, yes?
when logging on, w95 registers a _unique_ netbios name USERNAME<03>,
_not_ a group name as i first thought.
all unique netbios names registered with the samba WINS service are

i can only presume that the microsoft WINS service handles unique <03>
netbios names in a specific manner (similar to the way that it handles
the registration of <1d> unique names: it responds positive, and then
