In this Article, I am going to explain how to rename the Domain Controller.
As an Administrator, Renaming Domain Controller is not right way but in some cases it is required due to some previous wrong names.
Current Host name of the Domain Controller
Since the name assignment was wrongly provided, we cannot simeply rename as we do in work stations because this is domain controller. Hence we need to do it using NETDOM Command
Step 1: We need to add second name
netdom computername <CurrentComputerName> /add:<NewComputerName>
Step 2: make second name as primary name
netdom computername <CurrentComputerName> /makeprimary:<NewComputerName>
Now we have added second name and made it as Primary. Reboot the Domain Controller to get this applied.
After Reboot, you could see that now domain controller name has been renamed
Step 3: Remove the Old name
netdom computername <NewComputerName> /remove:<OldComputerName>
Now run DCDIAG or REPADMIN command to verify the Replication Status.
