Admin local account cannot login after joining a DC and being promoted to RODC

[LimiteCero]

Windows Server 2019 Datacenter.

After joining a machine a DC and promote to RODC the admin local account cannot login in the system.

Only Admin DC can login in the RODC.

The error showed is that password or username is incorrect wich is not true cause the local Admin account was not modified before joining the machine to the domain.

Any suggestion? 

Thanks!!

That's expected behavior. When a server is promoted to domain controller all local accounts are removed and transitioned to domain accounts.

Thanks a lot!
so how could I log in with a local admin account?

You cannot logon to a domain controller with a local account because since promotion local accounts do not exist.

Unless you're asking about DSRM mode.
