The first thing we are going to do is open up the Server Manager, it is located at the Taskbar. From here we can click on "Add roles and features".
Next, the Installation Wizard will appear on the screen. We want to select "Role-based or feature-based installation"
After selecting next, we will select a server to install the roles on, since this is the only server, this is the only one we can select.
After pressing next, we arrive at the Server Roles, here please select "Active Directory Domain Services." It will then display a popup window with a list of services that also must be installed as well, then click "Add Features".
After pressing next we can then select the features we want, it is advised that you add the SNMP Service or any other service needed.
From here, it is going to ask for a confirmation of what is to be installed.
After we press Install, we then have to start the remote registry service. Click on the Start, navigate to the Control Panel, then Administrative Tools, Services, then right-click on Remote Registry, click on Properties, and select Automatic on the Startup. After, select Start on the Service Status.
After that, we can navigate back to the Server Manager tab, click on the flag with the yellow caution sign and click on "Promote this server to a domain controller."
Next, a Deployment Configuration Wizard will appear and you can select the deployment operation "Add a new forest" and specify the Root domain name. After please press next.
Next we can specify the NetBIOS domain name.
Next we can change the default location of the Database, Log files, and SYSVOL folders if needed.
Finally review all of the prerequisites checks and verify that all are functioning properly.
Please keep in mind that a DNS service must be present on the network, if it isn't than the server will need to establish its own DNS server. After clicking install and no other errors are received, then you have successfully installed Active Directory on Windows Server!
