I have 2 production domain controllers, and wanted to add a third one, just in case. As we restarted for some roles we had some issues on boot that were resolved and now the AD is OK between the 2 DCs without any erros (already checked).
When trying to add this 3rd DC I have this error on the Verification phase: Verification of Administrator rights failed. The Administrator account does not have the "Enable computer and user accounts to be trusted for delegation" right enabled.
I didn't install the other 2 DCs. When I started there, they were already in place. On the DCs Default Policies, on that item, it's blank. I don't know of any other changes.
What might be causing this? I looked online and wanted to check if anyone share an issue like this from their history.
