The usual problems are:
1. failure to update the serial number.
2. Notify messages being sourced from the wrong address.
The address the message is sent from needs to match the
address in the masters clause. See notify-source and
allow-notify.
3. A NAT box not reflecting internal traffic.
See also-notify.
4. NS to address conversion is failing. Check that the
master can resolve the addresses of the nameservers.
5. The wrong nameserver is listed in the SOA record.
Named does not send NOTIFY messages to the nameserver
listed in the SOA record.
