Windows server 2012 R2 Promoted to Domain Controller
IntroductionIntroduction
If Windows 2012 or Windows 2012R2 play the role of Active Directory Domain Services, the domain controller must be upgraded to a domain controller. This document sets out the steps required to add a domain controller to an existing location.
How to Promote a Windows 2012R2 Domain Controller
For the inclusion of a role post, an option to promote a domain controller will be available. If the Server Manager is closed, it will need to be reopened. To do this, right-click on my computer and select Manage.
In the upper right corner, a warning label will now appear next to the job details icon. Click on this icon and select Promote this server in the domain controller.
The Active Directory Domain Services Configuration Wizard will start. In the example shown below, I am adding a new domain controller to an existing domain. In most cases, I use an Administrator account. However, in the example below, I use an account with the following three categories:
1.Domain administrator
2.Business Management
3.Strategic Management
As the new server used will replace one of the main domain administrators, DNS and Global Catalog have been selected. Additionally, I have used the Directory Services Restore Mode (DSRM) password which is not compatible with the domain administrator. Although this password may be the same as the domain administrator, I chose not to use the same password for security purposes. Make sure this password is encrypted as this password can help access the environment in case all domain administrator accounts lose access.
n on the next screen, Active Directory can replicate itself from any domain controller or domain controller can be specified. In the screenshot shown below are three domain directories listed. Since two of these items will be removed from the job soon, a new domain controller was selected.
Windows will perform the required test first. If the user account used to promote the server does not have sufficient privileges (Schema Admin or Enterprise admin), the installation cannot be terminated. Either log into another account with the appropriate permissions or grant those permissions to the user you want and start from the beginning of the promotion wizard.
When the installation is complete and the wizard is closed, the AD DS will restart.
Once the server has restarted, FSMO roles can be transferred to the newly installed domain controller.
