I don't quite understand that sentence. The file is replicating but the
changes aren't (???)

How long have you waited and what is the REFRESH setting on the zone? If
there's something wrong with the NOTIFY mechanism for this zone, then it
could take up to REFRESH time for the changes to replicate.

If NOTIFY is broken, then that could be tackled as a separate issue.
Better to establish that normal REFRESH-timed replication works before
getting into the arcana of NOTIFY.

Probably just a stupid Wintel client that's misconfigured to register
its name in DNS.
