Hi,
Based on the error description, check the user account you attempted the upgrade is a member of the 'Schema Admins' and/or 'Enterprise Admins' groups. Make sure "Install-WindowsFeature RSAT-ADDS" is installed, you could ping DC from this computer successfully.
If the issue persists, I recommend you to follow the steps below for troubleshooting:
1. Please unjoin the domain at first.
2. Rejoin the domain.
3. Please refer to the below thread to run "setup /prepareAD" again on a forest DC, then let the changes replicate before upgrading Exchange server.
Prepare Active Directory and domains

Hi
I had a similar case last week where it listed all of the above because the server could not contact the domain controllers. After changing DNS to a different DC and a reboot all seemed fine.
Hope this helps. Please remember to click “Mark as Answer” on the post that helps you, and to click “Unmark as Answer” if a marked post does not actually answer your question. This can be beneficial to other community members reading the thread.
