Upgrade to 8.2.3 or, better still, 9.1.0. The version you're running
has security holes. See

If you'd told us the domain name, someone might have been able to
checked the zone's name servers. You say "notify doesn't work". What
does that mean? Does the master server send NOTIFYs? Does the slave
get them? Does the slave fail to respond to them? What's in the name
server logs on both systems? You will probably find the explanation
for the problem there.

If the zone's not getting propagated to the slave, there are many
possibilities. Maybe there's a connectivity or routing/firewall
problem between the servers. Maybe the master server isn't
authoritative for the zone because the zone file has syntax errors.
Maybe you forgot to increase the SOA serial number after updating the
zone file? Maybe the zone's NS records are messed up so the master
server doesn't know it has to send NOTIFYs. Maybe the slave has the
wrong IP addresses in the masters{} clause of its zone{} statement for
the zone.
