Note that "rndc retransfer <zone>" is fairly brutal. It tells the slave
to forget everything about its current copy of the zone, including its
SOA serial, and attempt a full zone transfer from the master(s).

In normal circumstances, a missed notify would be better dealt with by
"rndc refresh <zone>", which just expedites what would normally happen
when the refresh interval expires. That is, it will do an SOA query
against the master(s), and if the serial has increased attempt an
(if possible incremental) zone transfer.
