Windows Server: How to Use the Install from Media Option to Promote a Domain Controller Running Windows Server 2008 or Later

Article Summary: This article provides information about promoting a domain controller running Windows Server 2008 or later using installation media to minimize the initial replication of Active Directory data across the network.

As discussed in How to Create Active Directory Domain Services Installation Media Using Ntdsutil in Windows Server 2008 and Above, it is possible, and sometimes desirable, to use installation media to promote an additional domain controller (DC) in an Active Directory (AD) domain. Doing so avoids the need for the initial synchronization of AD data to occur over the network, which can be beneficial if the new DC is connected to the rest of the environment by a slow or unreliable link. See the above article for information on creating the installation media. This article details the process of promoting a DC using that media.

The information in this article applies to Windows Server 2008 and above. For information on a similar procedure in Windows Server 2003, see How to Use a System State Backup to Promote a Windows Server 2003 Domain Controller.

Since the main goal of promoting a DC using installation media is to minimize initial replication traffic across the network, the media used for the promotion should be as recent as possible, as any changes to AD objects that have occurred since the creation of the media will replicate across the network.

To promote a DC using installation media created from another DC, perform the following steps:

  1. Verify that the destination server (the server to be promoted) has access to the installation media.
  2. At an elevated command prompt, type dcpromo to launch the Active Directory Domain Services Installation Wizard.
  3. On the opening screen of the wizard, check the Use advanced mode installation checkbox and click Next.
  4. Click Next on the Operating System Compatibility screen.
  5. Select Existing forest and Add a domain controller to an existing domain, then click Next.
  6. Type the DNS name of the AD forest in the appropriate field and supply the credentials of a user account in the Enterprise Admins or Domain Admins group in the destination domain. Click Next.
  7. Select the domain in which the server will be a DC and click Next.
  8. Select an AD site for the new DC and click Next.
  9. Check the appropriate boxes if you wish the DC to be a DNS server, global catalog server, and/or read-only domain controller (RODC), and click Next.
    Note: The DC can only be an RODC if the installation media was created using an RODC-specific Ntdsutil command, as detailed in How to Create Active Directory Domain Services Installation Media Using Ntdsutil in Windows Server 2008 and Above.
  10. Select Replicate data from media at the following location and specify the location of the installation media. Click Next.
  11. When installing from media, some data must still be copied from an existing DC. Select a DC from which this data will be copied, or let the wizard choose one automatically. Click Next.

    The following steps will not differ from a normal DC promotion.
  12. Specify the storage locations for the AD database, transaction logs, and SYSVOL folder, and click Next.
  13. Specify a Directory Services Restore Mode Administrator password and click Next.
  14. Review the summary and click Next to begin the promotion.
