As far as I know, NT replies correctly to name queries and node status
queries (both on port 137). The help generated by 'nmblookup -?' state
that it's only W/95 that has this problem, and I think it's only early
versions of W/95, and only when sent a Node Status query.
I have a test machine at home which runs W/95, responds correctly to a
Name Query, but responds to port 137 when sent a Node Status.
