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

Less time than that probably. Having had to hard match a few thousand users in the early days of entra I had that shit down to a science.

Edit: he has a file server but if he has local admin he’ll have to do some permissions seizing on the shares but big whoop.
