Well we changed things by creating separate zone files for each view,
but that made no difference to the original problem. However, you are
absolutely right, the notifies were only being seen by one view (logging
the notifies and transfers showed this).

That is exactly what we saw. The SOA serial numbers were different, but
every so often they would get 'closer' - this was when the refresh
occurred.

It has been a bit convoluted but we have the notifies working correctly
now as well :-) The zones show the same SOA serial number regardless of
whether inside the campus, outside, or at one of the remote secondaries,
and they remain consistent after an update.

Many thanks to people for the replies.
