[Samba] named ( bind 9.9.4 ) fails to start

[Maton, Brett]

Hi,

  I removed a couple of dead DC's from my domain using this command:

samba-tool domain demote --remove-other-dead-server=<dc name>


  I then restarted named on the remaining server, but it failed to start
with the following errors in messages:

named[30255]: samba_dlz: configured writeable zone 'x.x.x.in-addr.arpa'
named[30255]: samba_dlz: configured writeable zone 'x.x.x.in-addr.arpa'
named[30255]: zone mydomain.com/NONE: has no NS records
named[30255]: samba_dlz: Failed to configure zone 'mydomain.com'
named[30255]: loading configuration: bad zone
named[30255]: exiting (due to fatal error)
named[30255]: samba_dlz: shutting down

samba-tool fsmo show lists all service as being owned by the remaining
server.

What should I do next ?
