Dynamic DNS nsupdate

[Kevin Darcy]

The only nameserver it could find for the "intranet" zone was "daemon.intranet", but it couldn't find
an address associated with that name, so it gave up. You appear to be missing an A record in the
"intranet" zone and/or the necessary "glue" A record in the root zone.
