Secondary DNS does not resolve the nslookup client requests when the primary DNS is off.


Greetings to all.
I have the following problem.

I am configuring a master DNS zone in Windows Server 2012 and a slave DNS zone on CentOS 6.7 .
I already did the zone transfer Windows Server to Linux the which it was satisfactory already may I find the file specified in the slave zone with the records the master zone.

The configurations for server are as follows:

1) The Windows Server 2012 server has as name apple1 and an IP of 10.10.10.1
2) The CentOS server has as name apple and an IP of 10.10.10.2

When I turn off the primary DNS server and run nslookup on the secondary DNS server responds correctly.



Quote:
[root@apple usuariocc]# nslookup
> pc1
Server: 10.10.10.1 Primary DNS server on
Address: 10.10.10.1#53 Secondary DNS server on

Name: pc1.itssnp.edu
Address: 10.10.10.3
> pc1
Server: 127.0.0.1 Primary DNS server off
Address: 127.0.0.1#53 Secondary DNS server on

Name: pc1.itssnp.edu
Address: 10.10.10.3
>

But the problem this when run nslookup from a client in this case I use a client with Windows 10 I assign IP manually as well as preferred and alternate DNS.

Now if I put the secondary DNS instead of the primary DNS ,the clients are able to successfully execute the same request.

Can you clearly state the problem in one sentence?

When I turn off
the primary DNS and I make nslookup
in the customer
The secondary DNS does not resolve the request.
it appears as
"ran out the waiting time of the request"

Depends on the Windows configuration - does it have the secondary server listed?
