Installing a Windows Server 2012 Domain Controller

Many of our current customers are still running Windows Server 2008 and Windows Server 2008 R2 Domain Controllers and they are looking to replace these servers with Windows Server 2012 Domain Controllers to utilize the new features of Windows Server 2012. You might also be looking to replace your aging Windows Server 2008 and Windows Server 2008 R2 Domain Controllers with spanking new Windows Server 2012 Domain Controllers, while keeping your Active Directory running smoothly.

Before detailing your Active Directory migration, I felt it would be pertinent to discuss how to add a Windows Server 2012 Domain Controller to an existing Active Directory Domain first.  Migration of Active Directory from Windows Server 2008 to 2012 would be the next step once this procedure has been completed successfully.

Getting Started

1. Setup and install your Windows Server 2012 machine.

2. Configure the new server’s IP address to correspond to the target domain and ensure the existing Domain Controllers, where DNS is installed and configured, are visible by your new Windows Server 2012 install.

Setting Up Domain Controller Functionality

1. Open the Server Manager console and click on Add roles and features.

2. Select Role-based of featured-based installation and select Next.
3. Select the Active Directory Domain Services role.
4. Accept the default features required by clicking the Add Features button.
5. On the Features screen click the Next button.
6. On the Confirm installation selections screen click the Install button. PLEASE NOTE: Check off the Restart the destination server automatically if required box to expedite the install should you be able to reset the target server automatically.
7. Click the Close button once the installation has been completed.
8. Once completed, notification is made available on the dashboard highlighted by an exclamation mark. Select it and amidst the drop down menu select Promote this server to a domain controller.
9. Select add a Domain Controller into existing domain.
10. Ensure the target domain is specified.  If it is not, please either Select the proper domain or enter the proper domain in the field provided.
11. Click Change, provide the required Enterprise Administrator credentials and click the Next button.
12. Define if server should be a Domain Name System DNS server and Global Catalog (GC). Select the Site to which this DC belongs to and define Directory Services Restoration Mode (DSRM) password for this DC.
13. Click the Next button on the DNS options screen.
14. In the Additional Options screen you are provided with the option to install the Domain Controller from Install From Media (IFM). Additionally you are provided the option to select the point from which DC replication should be completed. The server will choose the best location for AD database replication if not specified. Click the Next button once completed.
15. Specify location for AD database and SYSVOL and Click the Next button.
16. Next up is the Schema and Domain preparation.  Alternately, one could run Adprep prior to commencing these steps. However, if Adprep is not detected, it will automatically be completed on your behalf.
17. Finally, the Review Options screen provides a summary of all of the selected options for server promotion. Click the Next button to continue.
18. Should all the prerequisites pass, click the Install button to start the installation.
