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.

Your generosity helps pay for the ongoing costs associated with running this website like coffee, hosting services, library mirrors, domain renewals, time for article research, and coffee, just to name a few.
