And yes, I like this question, because I don’t want to stress the principal NS and I want to setup more services like Nextcloud running in another NS hardware.
So, excuse me to ask here, but seems related:
If I have one NS running as a AD/PDC, how can I have a second NS as backup for authentication when the first is down (maintenance, etc.)
I ask, because yesterday, something goes wrong and I lost the authentication on my only one NS (AD), something like a DoS, maybe caused by a excess of log with Samba Audit + Antivirus accessing the shared folders.
So I wonder if I can setup a secondary NS using my own computer that I got always running with virtualbox. With the purpose of authentication for our AD users, it is possible and how to setup a joined secondary AD server for this kind of emergency?
mmmh, need to read this Join an existing Active Directory domain
Not enough, need to find what I’m looking for: “Add a slave AD with NS on an AD/NS” ?
