This article provides information on restoring a Windows Server 2012 domain controller from a backup.

This article assumes that the backup was created using the built-in Windows Server Backup utility. The procedure for recovering a DC using other backup software may differ from the procedure given here. Consult the documentation for the backup software for specific instructions.
 



If an Active Directory domain controller (DC) running Windows Server 2012 is unable to boot into normal mode or Directory Services Repair Mode (DSRM), it may be necessary to restore the DC from a backup. The procedure for doing so is similar to the procedure in Windows Server 2008 R2, but the Windows Recovery Environment (WinRE) interface has changed. A full restore can still be performed within WinRE.


 

Note: If the only available backup contains the system state and no other data, it is still possible to restore the DC by installing the operating system, adding the Windows Server Backup feature, and restoring the system state. This article focuses on performing a full recovery of a nonfunctional DC, however.


To restore a DC running Windows Server 2012 from a backup, perform the following steps:

  1. Boot the server with the OS media in the DVD drive and press any key when prompted.

     
  2. Choose the appropriate language options, time and currency format, and keyboard layout, and click Next.

After the server boots, it is a good idea to review its event logs to verify that everything is functioning properly. Note that some errors can be ignored if they only occur during or shortly after the boot process.
