One question , If i have shuted down the servers so i can't devote them, what should i do ??
You will have to clean-up your Active Directory and remove the domain controller objects from there.
I don't have a guide for doing this, unfortunately.

I have a question. How does someone go about downsizing lets say 147 DC controllers to lets say 18 DC? like I am trying to grasp the process. Like why would we need to do this? Thank you !
If you're looking at removing over 100 domain controllers, I would recommend speaking with a local IT services provider and getting their advice if you are unsure.
This is something that needs to be thoroughly mapped out and planned, as it will cause a lot of issues if it's not done correctly.
Without knowing any of the details, I can't really provide any information, unfortunately.

Role change is in progress or this computer needs to be restarted
How do I fix this?
This isn't an error I've seen before. Have you tried restarting?
Thanks for watching!
@@danny_moran Turns out it was due to updates that were stuck. Cleaned that up and it worked.
Glad you've got it working!
I keep getting "This active directory domain controller appears to be the last DNS server for the following active directory-integrated zones" and won't demote...
Do you have other domain controllers and dns servers in the domain?
@@danny_moran Yes, I was removing a 2012 and replacing with a 2022...I ended up using powershell to demote it. The GUI never gave me the option to remove DNS delegation, and when I ran the PS script it kept failing on that, so I removed that piece of the script and it successfully demoted it.
Glad you got it demoted in the end.
Thanks for watching!
