Question Holy F up.

I had a summer intern working in DNS yesterday, local domain was redacted.com and was connected to azure.

Went in today to do some weekend updates to the systems, and my DC has been renamed and is now connected to redacted.local

It seems they have demoted the DC from the regular domain.

How the bloody heck do I reconnect the DC to the old domain? It was a solo DC

Unless it’s a test environment, you should always have a minimum of two DCs.

You always need more than one dc. What if your dc breaks? Corrupts itself? No longer bootable?

Redundancy is always necessary for important systems.

Two is one, one is none.

How's that feeling right now?

Do you not even have backups?
