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
2) The CentOS server has as name apple and an IP of

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

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

> pc1
Server: Primary DNS server off
Address: Secondary DNS server on


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.

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?
