When operating an Active Directory Domain environment, it is a good idea to configure more than one domain controller for redundancy in case something should happen to one of the servers. This guide will show you how to add a new domain controller to an existing Active Directory domain.
- Log onto the new server as an administrative user.
- Be sure to configure your basic options such as a static IP address, the hostname of the server and if desired, enable remote desktop for administration.
- Open the Server Manager
- On the Dashboard, click Add Roles and Features
- Click Next on the Before you Begin page
6. Make sure that Role-based or feature based installation is selected, then click Next
7. Select the server that you will be installing the role on, then click Next
8. Locate and Select Active Directory Domain Services and click Add Features on the popup window. Click Next.
9. Click Next on the Add Features Window
10. Review the information on the AD DS screen, then click Next
11. Choose to Restart Automatically or not, then click Install
12. After the installation has completed, click Close.
Post Deployment Role Configuration
Once the AD DS role has been installed, we will need to complete the configuration.
- In Server Manager, locate and click on the Notifications Button
at the top right side of the screen. - Click Promote this server to a domain controller
- On the Deployment Configuration screen, choose Add a domain controller to an existing domain, then enter the domain name and credentials. Click Next.
- Select the Options for the new domain controller and enter a DSRM password, then click Next
- Click Next on the DNS Options screen
- Allow the domain structure to replicate from an existing domain controller, then click Next
- You can change the location of the AD files, but the default options are fine. Click Next
- Review the information and click Next
- The wizard will go through a prerequisite check. Review the information, then click Install
The server will then install the roles and go through the domain promotion process and restart. After the server is back online, verify that the SYSVOL and NETLOGON shares are present on the server, then verify that the DNS forwarders are also replicated.
