dhcp Unable to add forward map from..connection refused

[Lyle Giese]

You are telling dhcp to talk to your DNS server at ip address
192.168.1.250 and it's not listening on that ip address. According to
your named.conf, it's only listening on 127.0.0.1.

Plus you need an A record for ns.localzone.local.
