Hello All,
I am trying to add a 2019 server to our existing domain and it gives me this error:
verification of replica failed. the forest functional level is not supported. To install a Windows Server 2019 domain or domain controller, the forest functional level must be Windows Server 2008 or higher.
We are currently functional level is 2008 R2.
Restarted the new server to no avail. According to everything I have researched this should work.
Any insight would be a great help
Thank you :)
