How to add Windows Server 2012 as a Domain Controller?
In this post we are going to cover how to install and Add Windows Server 2012 as a Domain Controller.
Up until Windows Server 2008 R2 we were able to use the command “dcpromo” to make a server a domain controller. But from Windows Server 2012 dcpromo is no longer available.
We have to use the Server Manager to install Active Directory Services and then Promote the Server to Domain Controller. Below are the steps.
3. The Add Roles and Features Wizard will launch.a. Make sure your Administrator Password is strong.
b. Make sure you assign a static IP address to the server.
c. Windows Server 2012 is updated with latest security updates.
6. Select “Active Directory Domain Services.
8. Select any features if required. Click on Next.
9. Active Directory Domain Services Wizard will start. Click on Next.
10. Select Restart the Destination server automatically if required and click on install.
11. Windows will start the installation of the Roles and Features you have selected, and restart if and when required.
12. After Installation finishes, you will get the option to promote the Server to a Domain Controller.
13. Active Directory Domain Service Configuration Wizard will start, Select “Add New Forest”. Enter the Domain name you require. E.g. wackytechtips.com Click on Next.
14. Select Forest and Domain Functional Level as Windows Server 2012, If you have any server in the network that is Windows server 2008 then select appropriately as Forest and domain function levels cannot be changed and if You select Windows Server 2012 as the function level you cannot add a Windows Server 2008 / 2008 R2 to this domain. Enter a strong DSRM (Directory Services Restore Mode) password. Click on Next.
17. If you have more than 500 servers & domain members its recommended to have the Database, Log files and SYSVOL folder on a different hard disk. For testing purposes we keep this at default. Click on Next.
19. Make sure that you don’t get any errors and have cleared all Prerequisites. Click on Install.
Configuring Reverse Lookup Zone after installing Active Directory Domain Services
After you finish installing AD DS you will have to configure DNS with Reverse Lookup Zone to ensure that DNS works correctly.
Follow these steps:
You will now need to add a PTR (Pointer Record) for the Domain controller in the DNS Manager to ensure DNS recognized the DC and can reverse lookup.
2. Enter the IP address of the Server, in Host name enter the FQDN of the server e.g. dc.wackytechtips.com Click on OK.
You have successfully installed Active Directory Domain Services on Windows Server 2012. Created New Reverse Lookup Zone and Created a New Pointer Record in DNS.
