Looking up NetBIOS names

[Jim B]

Is it possible to ask a machine for its NetBIOS name if it's running either
Windows or Samba?

I tried a few various nmblookup and smbclient command lines to no avail.  I
would like to be able to query a machine (by IP) and have it respond with
its nb name.


I've noted that if I perform an smbclient -L -I on a machine, it will not
list its shares unless I get the NetBIOS name correct... which is why I'm
looking for a way to find its name.

TIA.
