[Samba] Samba trying to connect to a non-existant DC for NTP?

[James B. Byrne]

I am down to these last remaining artifacts, as far as I can discover:

samba-ldbsearch --cross-ncs --show-binary \
  -H /var/db/samba4/private/sam.ldb \
  -b 'DC=brockley,DC=harte-lyne,DC=ca' \
  | grep smb4-1
            mname                    : smb4-1.brockley.harte-lyne.ca
        ns                       : smb4-1.brockley.harte-lyne.ca
        ns                       : smb4-1.brockley.harte-lyne.ca

I tried deleting the NS RRs but could not arrive at the correct incantation:

samba-tool dns delete 127.0.0.1 \
  brockley.harte-lyne.ca \
  brockley.harte-lyne.ca \
  NS \
  'smb4-1.brockley.harte-lyne.ca.' \
  -U administrator
Password for [BROCKLEY\administrator]:
ERROR: Record does not exist; record could not be deleted.
zone[brockley.harte-lyne.ca] name[brockley.harte-lyne.ca]

How are these last remnants removed?

Thanks,
