Secondary DNS failover not working.

I setup a secondary Domain Controller/DNS server as a failover.
I stopped the DNS service on the primary and failover to secondary did not work.
Workstations could not obtain the secondary DNS server IP address.
It does work if you manually input the secondary DNS in the TCP/IP properties as the Alternative DNS server.

Well... Yes.... Of course.

This is the way it is supposed to work.

Computers can not know where to find a secondary DNS server if you don't indicate it in the IP configuration.
So you always should have at least 2 DNS servers IP addresses in the IP properties of any computer that needs DNS resolution !

Have a good day.

All the workstations are setup to automatic IP and DNS.
Is there a way to have the workstations automatically resolve the the secondary DNS if the primary DNS goes down?

If your station get their IP configuration dynamically  from a DHCP server then you must act on the DHCP range options to add a secondary DNS IP address.

There's only 2 solutions :

1) your stations have a static IP configuration and then you have to add the secondayr DNS IP address on the station.
2) your stations get their IP configuration from DHCP and then you must add the secondary DNS IP address in the DHCP range options.

That's how it is supposed to be. Nothing magical...
