samba - Jul 1998 - nmblookup question

I'm running Samba 1.9.18p8.  If I use nmblookup to query the name
of an NT server, as in

	nmblookup -A <ip address>
	
then a packet trace shows an RPC reply coming back and nmblookup
displays a list of names belonging to the NT server.  If
I try the same query on a Windows 95 machine, nmblookup only says

	Looking up status of <ip address>
	No status response (this is not unusual)

However, the packet trace shows an RPC packet again coming back
from the Win 95 machine, including the list of names I would have
expected nmblookup to display.

Why doesn't nmblookup report the names returned by the Windows 95
machine?

Thanks

P.S. debug level 4 output from nmblookup when querying the Win 95
machine:

nmb packet from <ip address>(137) header: id=11904 opcode=Query(0) 
response=No
    header: flags: bcast=No rec_avail=No rec_des=No trunc=No auth=No
    header: rcode=0 qdcount=1 ancount=0 nscount=0 arcount=0
    question: q_name=*<00> q_type=33 q_class=1
nmb packet from <ip address>(137) header: id=11904 opcode=Query(0) 
response=No
    header: flags: bcast=No rec_avail=No rec_des=No trunc=No auth=No
    header: rcode=0 qdcount=1 ancount=0 nscount=0 arcount=0
    question: q_name=*<00> q_type=33 q_class=1

Is there an option for nmblookup that will broadcast to the local network
and return the ip addresses and the netbios names of all the responding
machines?

Thanks,
