[Samba] nmblookup -B localhost __SAMBA__ failing on samba-2.2.3a

[GHCebulka at uss.com]

Server:   Samba-2.2.3a
OS:  Solaris 2.7

nmbd is failing to start from swat. After looking through the source code I
found that swat uses  "nmblookup -B 127.0.0.1 __SAMBA__" command to
determing whether nmbd is running or not.
#nmblookup -B localhost __SAMBA__
querying __SAMBA__ on 127.0.0.1
name_query failed to find name __SAMBA__

However, nmbd is running and I can see/use shares on my MS machines. When I
run nmblookup -B azure __SAMBA__, it works fine.
#nmblookup -B azure __SAMBA__
querying __SAMBA__ on 170.191.20.27
170.191.20.27 __SAMBA__<00>

What am I doing wrong here????
I've included the output from ifconfig -a and my smb.conf file.
Any help would be great,
     Thanks in advance,
