Well, if you are running Bind and have deleted 'dns-hostname', you are
going to have problems, but if you check the 'server services' line in
smb.conf, then if it isn't there, you are using the internal DNS
server, or if it is there and has 'dns' in it, you are using the
internal DNS server. If you have the line and it doesn't have 'dns' you
are using Bind, or if the line consists of just '-dns', you are using
Bind.
