It is. And "notify name servers " is  chosen.

Our slave servers are ns1.qnet.fi, ns2.qnet.fi and ns3.qnet.fi.  And the 
master win2003 server is xeon.merinova.fi.  The zone is merinova.local 
and example host xeonx.merinova.local.

At the moment ns3 is not responding to queries to merinova.local.

Also just made few updates to the zone, the serial in the master is 6240 
but the responding slaves ns1 and ns2 still report 6239.
