Yes, this appears to show netbios name.
[root@bacteria ~]# nmblookup -A 192.168.112.125
Looking up status of 192.168.112.125
        JAB-OPTI755     <00> -         M <ACTIVE>

I am not familiar with smbclient options and example usage.  Will have to 
look this up more, but a basic query gives the same error as BackupPC.

[root@bacteria ~]# smbclient -L jab-opti755
Enter root's password:
session setup failed: NT_STATUS_LOGON_FAILURE

I have been reviewing Chapter 10 (Network Browsing) of the Samba documents, 
and here is something that caught my attention.  I am not sure if this is 
something relevant to my issue, so I am hoping someone can enlighten me.

My Samba config does not include a name resolve order setting.  And looking 
at the original Samba config that came with the CentOS 6 installation, there 
was not one in that either.  I checked my old Samba Server (RHEL 3) and it 
was in the original config for that one, but commented out.  Is this maybe 
my problem, do I need to include the following line in my Samba config to 
complete a proper configuration?

name resolve order = wins lmhosts bcast host
