Nobody answered this.  It doesn't make sense to me that
samba_dnsupdate should be needed if samba is itself handling the DNS
records.  But maybe there is a reason that samba_dnsupdate is still
necessary.

As I said before, I've not tried this out.

OK, so it looks like it loaded the reverse zone.

This seems to have something to do with WINS:

http://tools.ietf.org/html/draft-levone-dns-wins-lookup-00

hmmm...  A zone needs an SOA record.

This is probably because there's no SOA record.  I have no idea why
there might not be an SOA record, though.  Especially since it was
working yesterday.

As mentioned above it seems to be something to do with WINS.

The unknown records are probably because of that, but I don't know if
your other problems are caused by that.
