I have 2 Zentyal domain controllers.

dc1 acts as main dns server, transparent DNS cache not enabled, forwarding to google root dns to resolve external addresses.

When dc1 is offline, I checked that can nslookup, set dc2 as the server and resolve both internal and external addresses, but it needs to be specified manually.

What are the best ways to automate this: router? client-side script? group policy?
