“A domain rename operation is already in progress”

When promoting a Windows Server 2012 R2 to a Domain Controller failed…

The other day, when I attempted to add a newly installed Active Directory to become the slave domain controller of a master, the error message “A domain rename operation is already in progress” was displayed. Promoting the Windows Server 2012 R2 server to a Domain Controller failed.

I was sure I never attempted to rename the original domain…

Assuming a domain rename operation was in progress (why?!), I ended that operation with rendom:

C:\>rendom /end
The operation completed successfully.

After this operation, I could add my new slave domain controller.
