There is a major step that is not included in this process. I doubt too many of us have an Active Directory domain with no member computers. If you follow this walk-thru completely, you will end up manually re-adding every workstation and server to the newly renamed domain. Not very efficient. To make this work correctly, you must pause before running "rendom /clean" and reboot all servers and workstations twice. Not power cycle; you must do a restart from the computer itself or "shutdown /restart" remotely. If you execute "rendom /clean" before all the machines in the domain get rebooted twice, they won’t be able to access the domain because "rendom / clean" removes the old domain name from Active Directory, including removing all values of ms-DS-DnsRootAlias from the domain name operations master. When you have rebooted computers that are members of the domain twice, run "rendom /clean" and then "rendom /end".

Thank you so much, you pretty much saved my SA course project from ending up a total disaster.

This worked well in my case, a new DC in Azure that hasn't been implemented yet. Thank you.

Hi Rohit. Thanks for the knowledge sharing. Do we need to change all endpoint Primary DNS suffix to a new domain name?

Also make sure you have a local admin user to login with incase you can't login with domain admin.

When i type the rendom / upload its getting error failed to upload dns root alias on the

[davehouser]

um, this did not migrate any of the DNS records from the old forwarding lookup zone to the new forwarding lookup zone. The forwarding lookup zone still exists and so do all the entries. Is this expected? How do I migrate these?

Did anyone try this? Is the 2019 exch server really supporting domain name change?

[VladCoolMan]

rendom it is not an internal or external command executable program or batch file what to do?

Does it work on Windows Server 2012 e 2012 R2?

[gerginadam]

What about old verisons of windows server? can we do that?

I tried this multiple times on a VMWare Window 2019 Server VM. After executing the rendom /execute command, I was unable to log in as Administrator, any other user . I tried both the old and the new domains. I would very much appreciate it if you had any guidance on this, otherwise this video was at best a waste of time.

Is there a way to rollback the name change if any issue reported?

FIRST HAVE A GOOD TESTED BACKUP OF YOUR DC!
--
I just did that procedure, here are my notes:

I did wait before the /clean to reboot all my clients (and servers) twice as suggested by @ckdunn12345.
DHCP server stopped working for no reason, Service had to be restarted
DHCP continued to push the wrong domain DNS suffix, had to change manually the DNS suffix in the DHCP options
During migration, some machines were not reachable and had to be either reached trough old scheme, new scheme or plain IP. After first client reboot, they got the new address and worked flawlessly.
Rebooting the switches and access points forced every client to re-register trough DHCP, saved a lot of issues.
