Demote Window 2012 DC

Hello,

I have recently added and promoted a new 2012 R2 DC in a Windows 2008 R2 environement

Everything went fine regarding this DC promotion. No replication errors

For different reasons not related to this promotion I need to re-format this server. After reformating this server I will need to promote it again  as a new DC

Questions:
- How do I demote the server (dcpromo do not exist in Windows 2012 R2? )
- can I give the server the same name or better give a new name ?

Thank you

To demote a 2012 Domain Controller you simply just need to remove the Active Directory Domain Services role within Server Manager:
In Server Manager > click on Manage on the top right > Remove Roles and Features > select your 2012 server from in the Server Pool > clear the Active Directory Domain Services check box > in the Validation Results window click Demote this domain controller at the bottom
If you are going to be rebuilding this machine then it's recommended you remove any other AD DS-related roles and features you may have installed:
- Active Directory Module for Windows PowerShell feature
- AD DS and AD LDS Tools feature
- Active Directory Administrative Center feature
- AD DS Snap-ins and Command-line Tools feature
- DNS Server
- Group Policy Management Console
