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.

Installing Virtual Box Guest Additions in Zentyal

I stumbled across Zentyal which seemed to be quite an interesting Linux distribution. I say that as they claim to be able to replace Microsoft’s Small Business Server (SBS) and co-exist with Active Directory and Exchange.

Have a look at their website for all the features.

I wanted to install the guest additions after installing Zentyal in Oracle’s Virtual Box to run the virtual machine in full screen mode. This was not as straight forward as I though it might be. Below is a video tutorial that I created to show how to install the guest additions in Zentyal. (Watch in HD and full screen)

Also note: the links below the video are for the sites I used to get this working.

Configuring Hyper-v Host Network Adapters for ISCSI Storage Connectivity with Powershell .

Chinny Chukwudozie, Cloud Solutions.

Windows Server 2012 R2 with PowerShell 4.0 has hugely expanded support for configuring multiple NICs on a Cluster/ISCSI Initiator node via command line. After deploying multiple Network Interface Cards on my Hyper-v host, it took me a while to figure out how to properly configure the NICS with PowerShell .

Prior to Windows Server 2012, NIC configurations could be accomplished with the GUI, Netsh command line utility or mainly WmiObject classes. The following cmdlets enabled me complete the configuration of multiple NICs on a cluster node:

List Available NICs on Host Server.

Get-NetAdapter -Physical


Rename Network Adapter for Storage/ISCSI Connection.

Get-NetAdapter -InterfaceIndex 15 | Rename-NetAdapter -NewName StorageNIC1


Set Private IP Address on Selected NIC.

Get-NetAdapter -InterfaceIndex 14 | New-NetIPAddress -IPAddress -PrefixLength 24 -AddressFamily ipv4


Disable Network Adapter Bindings.

Usually the Storage Network Adapter needs just the IPv4 TcpIp binding enabled:

PS C:\ Get-NetAdapterBinding -Name StorageNIC1

Name DisplayName ComponentID Enabled

Converting a User Mailbox to Resource Room Mailbox using PowerShell.

Chinny Chukwudozie, Cloud Solutions.

In past versions of Exchange Server, specifically Exchange 2003, managing Resource Room mailboxes was not exactly a straight forward process. In my organization at the time, to manage room Calendars and bookings for Conference rooms (they were not referred to as Resource Rooms at the time), we had to create mailboxes to represent the conference rooms.

It was not possible within Exchange 2003 Server to automatically process conference room bookings and scheduling on the server side . One had to create a client side outlook profile representing the room mailbox and keep that outlook profile constantly running on some box to ensure room bookings were auto processed.

Exchange 2010 SP1 changed all that with the ability to process all calendar processes Server side. After I completed the migration from Exchange 2003 to Exchange 2010 SP1, I started the task of converting the conference room user mailboxes to type Room mailbox…

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 🙂
