[BlueOnyx:15434] Re: Secondary dns problem on BO

[Janwillem Ronken]

Hi Chris
No you understood well.. NS1 is master, NS2 and NS3 are slave. Both get the
zones from the master, but NS2 gives the error when doing a DNS check.
All have the right entries in the gui and dig does work too for all records
on both NS2 and NS3.

Best regards
Jan

I'm a little confused so bear with me as I try and walk through this
with you.

Do I understand correctly that you have two servers, ns2 & ns3, and they
are both running secondary zones that are served from a third server
(presumably ns1)?   While ns3 is slaving the zones from ns1 as expected,
an identically-configured box ns2 is failing?

If that is the case then my suggestion would be to check the ns1 server.
  From Server Management > Network Services > DNS, click on the Advanced
tab.  Make sure that your ns2 server's MAIN IP ADDRESS is configured in
the box that says "Zone Transfer Access by IP Address" and then Save.
If your ns2 hostname is configured on a secondary IP address of another
server, don't use that secondary IP in the Zone Transfer Access box.
You want to use the primary IP of the ns2 server.

I hope that I have not completely misunderstood your situation and
baffled you with bad advice.
