Error Demoting Domain Controller

[wirestyle22]

I logged into a domain controller on the root domain using enterprise admin credentials and was able to edit fSMORoleOwner in the Attribute Editor. I then attempted to demote the Domain Controller again and got past the initial error, but it then gave me an access denied error. I had already gone into sites and services to disable the deleted protection so I spent a long time trying to figure out why this was occurring. It simply had not replicated to the DC yet.

Domain Controller successfully demoted.

Big shoutouts to @Dashrender for going completely out of his way to help me resolve this issue. Can't thank you enough man.

I'm trying to do this now and my ADSI edit doesn't show the ForestDNSZone. Assuming my TLD/Domain was contoso.com, I should be plugging in this, right? No worky... Not sure why.

Are you working on a single domain or one root domain with multiple subdomains?

Single root. No subdomains.

Single root. No subdomains.

Your screenshot looks right to me. What does it say when you click OK

Do you see any DC's listed in the computer dropdown shown below? Might need to manually select a server. It should be able to see itself.

Yup. Oddly, not all of them. Out of 1 RODC and 5 DCs, only 2 show in the dropdown.

@Grey You don't even want to know what my network looks like. It's held together by bubblegum

You don't even have duct tape? It's time for an upgrade!

I just want to get to the root cause of the FSMO error you mentioned at first. I'm doing a dcpromo to remove a DC and getting the 'missing mandatory information' yet I can see that my FSMO/RID/etc. roles are all being handled by the proper server through the ntdsutil, AD sites & services and in the various other AD tools. The only thing left to determine is what is in my scheme or something that's not providing the detail for the dcpromo tool. I know that I can run it with a /force switch, but I'd rather find the root cause so I have an answer instead of a workaround.

(*&@^$(@ Thing. Apparently, you need spaces in between the commas. This is dumb, though. Some places, this doesn't matter and others, you can't have spaces, and then this requires a space. Stupid thing.
