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>
WORKGROUP <00> - <GROUP> M <ACTIVE>
JAB-OPTI755 <20> - 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
