As others have said, you MUST increment the zone's serial.
Addtitionally, on the master you may want to add "notify yes;" to the
zone stubs. This will make sure bind sends out a message (notification)
to the slaves when a zone is changed.
As previously noted, you have to increase the serial number of the zone,
plus in the secondary, in the conf file, you have to make sure that the
ownership and permissions are correct.
Permissions - good point. Modifying slave serials??? Er, no. Don't do
that. I'm pretty sure you weren't suggesting the OP do that....but
that's how it reads[1] :)
Ip source of the update matters too
Usually only a problem when you have a firewall that's matching the
source IP of TCP/53 connections (zone transfers always happen over TCP).
But seeing as the OP can refresh the zones after hosing the slave's
cache, I doubt this is a network problem.
Overall, Dns is easy to debug in the log files…
