[Samba] A device attached to the system is not functioning -When adding a computer to the domain

[Chris Beach]

Thank you, I'll give it a read and do some more research on it.. To be
honest my predecessor set up Samba before I got here (6-7 years ago), so
that's what I was left with (BLAH.COM), and not knowing any better, have
used it ever since.

Just FYI, my Domain name (workgroup in smb.conf) is BLAH.COM ... the netbios
name of the actual samba server is HAPPINESS
