You can only do zone transfers from authoritative hosts, and only if they allow
you to -- zone transfers are allowed to everyone by default, but can be
restricted by "allow-transfer". You should check whether you have any
"allow-transfer" clauses on the servers you are querying, and, if so, whether
the client is permitted to do a zone transfer from that nameserver.

If the machine configured as master is not answering authoritatively, that's
because it didn't load the zone properly, probably because of a syntax error or
the violation of some rule like "CNAME and other data". Check the logs on the
master from load time.
