This article is written for those who were searching for a detailed and simple for the understanding guide on how to install Active Directory Domain Services на Windows Server 2012 R2.

In this guide, we will consider the case when you already have a server with Windows Server 2012 R2 installed on it.

You can read more about how to install Windows Server 2012 R2 in my guide «Installing Windows Server 2012 R2». You can learn how to install Active Directory Domain Services on Windows Server 2008 R2 by reading «Installing Active Directory Domain Services on Windows Server 2008 R2».

I always recommend using English editions of Windows Server. As practice shows, the original (English) versions of Windows work more stable, moreover, it will be easier for you to communicate in the same language with professionals in case of problems or if you want to exchange experiences.

Before you begin installing the Active Directory Domain Services role, you must give the server the correct name in accordance with the standards of your organization, and then specify the static IP address, subnet mask, gateway, and DNS server address.

Go into the system under an account with administrator rights and on the keyboard press the key combination “Win” and “X”, then select “System” in the menu that opens.

Next, in the “System” window, in the “Computer name, domain, and workgroup settings” section, click on the “Change settings” button.

In the “System Properties” window on the “Computer Name” tab, click on the “Change” button.

I strongly recommend that you consider in advance how the servers in your organization will be called.

Next, indicate the new server name in the “Computer Name” field and click on the “OK” button.

The system will warn that to apply the new settings, you must restart the server.

Click on the “OK” button.

In the “System Properties” window, click on the “Close” button.

Now the system will offer to restart the server for the new settings to take effect.

Click on the “Restart Now” button.

Next, the server will restart.

Now you need to register a static IP address in the network connection settings.

Go into the system under an account with administrator rights and on the keyboard press the key combination “Win” and “X”, then select “Network Connections” in the menu that opens.

Now right-click on the “Ethernet” network connection and select “Properties”.

Select “Internet Protocol Version 4” and click on the “Properties” button.

Next, select “Use the following IP address” and specify a free IP address, subnet mask and gateway. Please note that you must understand in advance how your network is structured and know which IP addresses are free.

In the “Preferred DNS server” field, specify the IP address of this server, since the “DNS Server” role, which is installed together with the “Active Directory Domain Services” role, will be present on your server.

Click on the “OK” button.

In the “Ethernet Properties” window, click on the “Close” button.

Now you are ready to install the Active Directory Domain Services role.

Open the “Server Manager”, click on the “Manage” button in the upper right corner of the screen and select “Add Roles and Features”.

Click on the “Next” button.

Select the installation type “Role-based or feature-based installation” and click on the “Next” button.

Next, select the server on which the role will be installed.

Click on the “Next” button.

Select the “Active Directory Domain Services” role.

In the next step, the Role Installation Wizard will warn you that you need to install several components to install the Active Directory Domain Services role.

Click on the “Add Features” button.

At this point, choosing the DNS Server role is optional. It will be installed later.

Click on the “Next” button.

At the stage of adding components, leave all the default values.

Click on the “Next” button.

Further, the Role Installation Wizard invites you to learn more about the Active Directory Domain Services role.

Click on the “Next” button.

In order to start the installation of the selected role, click on the “Install” button.

The installation of the selected role and the necessary components for it began.

The installation of the Active Directory Domain Services role is complete.

Now click on the button “Promote this server to a domain controller” in order to increase the role of your server to the level of a domain controller.

I strongly recommend that you consider in advance which domain name you will use when adding a new forest.

This guide discusses adding a new forest, therefore, in the “Active Directory Domain Services Configuration Wizard” window, select “Add a new forest” and in the “Root domain name” field, specify the desired name for the root domain.

Click on the “Next” button.

The next step is to choose the functional level of the new forest and root domain. If you add a new forest and plan to use servers based on the Windows Server 2012 R2 operating system in the future, then you can not change the functional level of the forest and the root domain.

Specify the password for DSRM (Directory Service Restore Mode – Directory Service Restore Mode) and click on the “Next” button.

At this point, the AD DS Configuration Wizard will warn you that delegation for this DNS server cannot be created.

Click on the “Next” button.

Next, you can change the NetBIOS name that was assigned to your domain. I recommend leaving the default NetBIOS value.

Click on the “Next” button.

Now you can change the paths to the AD DS database directories, log files, and the SYSVOL folder. I recommend leaving these defaults.

Click on the “Next” button.

The next step displays a summary of the server configuration.

Click on the “Next” button.

Next, the “AD DS Configuration Wizard” will check whether all the prerequisites are met and display a report.

The message “All prerequisite checks are passed successfully” means that all requirements are met.

Click on the “Install” button.

The process of increasing the server role to the level of a domain controller has begun.

After the role of your server is upgraded to the level of a domain controller, the server will automatically reboot.

Before the server starts to reboot, you will see a warning.

The promotion of the server to the domain controller level is completed.

You can use the Active Directory Administrative Center or the Active Directory Users and Computers snap-in to manage users, groups, and other Active Directory objects.

Log in under the account with the rights of the domain administrator.

Open Server Manager, click on the “Tools” button in the upper right corner of the screen and select “Active Directory Administrative Center”.

The Active Directory Administrative Center opens.

You can also use the Active Directory Users and Computers snap-in familiar to many users to manage users, groups, and other Active Directory objects.

In Server Manager, click on the “Tools” button in the upper right corner of the screen and select “Active Directory Users and Computers”.

The Active Directory Users and Computers snap-in opens.
