Building an Exchange 2013 LAB Environment using Windows Server 2012 from scratch – Part 2: Active Directory Domain Controller: AD Installation…

In the previous part of this series (Part 1) I took you through to the point where you now have a basic Hyper-V guest which can be used as the domain controller for your Exchange 2013 Test Lab. In this part I would like to take you through how you can install Active Directory on that guest machine.

Now it is important to note that the process of installing AD on Windows Server 2012 is very different to previous versions of Windows. In versions of Windows from 2000 through to 2008R2 it was as simple as dropping to a command line and typing “DCPROMO” – but in Windows 2012 DCPROMO has been depreciated. You can type it in – but you will be told to use the Server Manager to perform an install of Active Directory Domain Services.

You can use the Server Manager to install Active Directory (but where is the fun in that?) – so, you guessed it – you can also use PowerShell.

So for the purposes of this article in the series I decided to write an Powershell automation script for the installation of Active Directory on the domain controller in our LAB.

As I said you can use the GUI – but I personally found that Powershell was quicker and less cumbersome.

Active Directory Installation Script

You can download the script from the link provided in the Download section below – or copy and paste it to your Guest Machine from the Script section.

Remember that this script is only designed for the following scenarios:

  • Creating a new forest
  • Creating a new domain
  • Promoting your VM to a domain controller

It should not be used to add a domain controller to an existing forest / domain.

The script performs the following actions:

  • Imports the ServerManager Modules (to allow for the add-WindowsFeature cmdlet to function)
  • Installs the AD-DOMAIN-SERVICES role and the management tools
  • Imports the ADDSDeployment module to allow for the configuration of Active Directory Services (after they have been installed)
  • Defines a function that uses the Install-ADDSForest cmdlet which accepts the following parameters:
    • Directory Database Path
    • Directory Log Path
    • Directory SysVol Path
    • The AD Domain Name
    • The NetBIOS domain Name
  • Gets the above values from the user
  • Creates the Database, Log File and SysVol folder structure
  • Installs Active Directory Services

If you examine the script you will see a number of other parameters that are used in conjunction with the Install-ADDSForest cmdlet – these are as follows:

  • -DomainMode – this configures the Domain Functional Mode that the first domain (that the script creates) is configured to work under. The script configures this to be “Win2012”.
  • -ForestMode – This configures the Forest Functional Level for the test LAB – the script sets this to be “Win2012”.
  • -CreateDnsDelegation – (as per Microsoft) Indicates whether to create a DNS delegation that references the new DNS server that you are installing along with the domain controller. Valid for Active Directory-integrated DNS only. The default is computed automatically based on the environment. The script sets this to false.
  • -NoRebootonCompletion – Instruct the Install-ADDSForest cmdlet to either reboot or not reboot automatically – the script has this set to $true, which means that you will need to reboot manually after completion.

Installing Active Directory on your Windows 2012 Domain Controller

In order to install Active Directory on the LAB domain controller – I downloaded the above script to my VM guest (well actually I wrote it on the Domain Controller; but you get what I mean).

Before you use the script in your environments you will need to ensure that your server’s Powershell execution policy is set to “RemoteSigned” – see the following article that I posted here for further information.

Then open a Powershell console window and navigate to the location where the script is located on your VM, and type the following:

.\instADWindows2012.ps1

19-01-201313-17-37

The script will then execute – firstly it will install the Active Directory Domain Services role and management tools and then it will prompt you for the DNS domain name for your AD domain. In my Lab I have used “artTest.local

19-01-201313-18-02

The script will then prompt you further for the following information:

  • NetBIOSName for the domain
  • Location of the Directory database (this MUST NOT have a trailing slash at the end)
  • Location of the Directory Logs (this MUST NOT have a trailing slash at the end)
  • Location of the Directory SysVOL folder (this MUST NOT have a trailing slash at the end)

19-01-201313-19-22

You will be prompted for the “SafeModeAdministratorPassword” – this is the equivalent of the traditional “Directory Services Restore Mode” Password of old but can also be used when starting the Domain Controller in “Safe Mode”.

19-01-201313-19-53

You will then be asked to confirm that you wish for the installation process to configure your server as a domain controller – confirm with “Y” to continue.

19-01-201313-20-12

The Install-ADDSForest cmdlet will then continue with the installation of the Director Services on your domain controller.

19-01-201313-20-29

During the configuration you may see a number of warnings similar to those in the example below – these can be safely ignored as this is a test Lab that will only consist of Windows 2012 machines and no other DNS servers.

19-01-201313-20-49

When the process has completed you will be presented with a short summary of the actions completed. You will need to reboot your VM.

19-01-201313-21-39

To reboot the machine – type:

Restart-Computer

At the management shell prompt.

In the next part

We are getting nearer the “sexy” parts in terms of Exchange 2013, however I will be focussing on installing Certificate Services on your new Domain Controller.
