How to decommission a Windows 2012 Domain Controller and Active Directory

I’m currently busy testing a few things and copied my lab DC’s virtual disk to 2 other machines. I need to decommission Active Directory on these two machines and thought that I’d share the steps on here.

First off the Domain Controller is decommissioned and then Active Directory is decommissioned. Note that the server is the only DC in my network which means I’m also showing the step to decommission the last DC in an AD environment.


How to promote Windows Server 2012 to a Domain Controller

Microsoft has done away with dcpromo when it comes to Windows Server 2012.

We’ve been so accustomed to using dcpromo that I actually struggled a bit to promote a 2012 server to a DC in one of my labs. This short video shows how to install the Active Directory Directory Services role on the server and that there is a small step you need to complete after the installation as just installing the role does not promote your server to DC status.

This small step cost me 5 minute of head scratching and going back to my training manual. Easy to forget and find but here’s a quick how to.

I’m not an AD expert but it’s good to practice this once in a while as you might get tasked to “quickly” set-up an environment for a client and practice makes perfect 🙂
