I think I figured it out, I think my non-sanitized name was too long and 
was causing problems, that or a misconfiguration of my /etc/hosts.

Either way, it's working now, and I appreciate your help.

As a side note, I was reading much older posts from you about dns stuff 
and found you referring to systemd among other things. Between that and 
bottom posting I feel encouraged that not everybody just goes with the 
flow.  My samba implementation runs on Slackware, so no systemd for me 
either.
