Active Directory

If Primary Domain Controller of Windows 2000/2003 Active Directory goes down and Backup Domain controller automatically takes over, then Active Directory will be out of Sync after Primary Domain Controller is restored from a backup

If you have Acronis True Image Echo Management Console installed on a machine with Active Directory and running Windows Server 2008, installation of remote components is impossible

To migrate a domain controller, back up with VSS and use Acronis Universal Restore for recovery

An attempt to connect to an Acronis Agent fails with "Active Directory is not available for the specified user. Cannot create MAPI profile. Probably, the user does not have a mailbox or Microsoft Exchange MAPI and CDO are probably out of date."


  1. You are backing up your Domain Controller with a single-pass backup.
  2. Backup fails with:

Error code: 41
Module: 307
LineInfo: e6792a5ee190dda6
Fields: $module : agent_protection_addon_vs_38573
Message: Failed to execute the command.
Error code: 54

If a Macintosh client attempts to connect to an Acronis Files Connect (formerly ExtremeZ-IP) DFS root volume from a network subnet that is not assigned to a site in Active Directory, you may see this error message in the Acronis Files Connect debug log. "Unable to determine site index for ip address x.x.x.x. This user will not be able to access DFS shares on volume X"

Back up Active Directory with Microsoft Ntbackup, then back up the server using Acronis True Image. Restore the server first with Acronis True Image, then restore Active Directory with Microsoft Ntbackup

The reason is that the backup was created with disabled VSS support


  1. You are installing Acronis Agent for Windows on a read-only domain controller (RODC);
  2. The installation fails;
  3. In the installation log there is a message similar to the following one:
    • If you selected to use an existing user for Acronis services:

      AddUserToLocalGroup: add user 'DOMAIN\administrator' to the group ''Backup Operators' failed with error '' (1313720)

Use application-aware backup for Active Directory


  • Your Management Server is running on a Domain Controller
  • You log in to Acronis Cyber Protect web console
  • You try to add an administrative account and enter the credintials

AcronisInfo is a utility that automatically gathers User Rights Assignment list, Windows Event Log, Msinfo32, Acronis registry keys, Acronis logs, Acronis Scheduler report, Acronis Disks Report and list of user’s Active Directory groups

You can make Acronis True Image execute manually created batch files before and after the backup or restore

In an Active Directory domain, one can grant rights for an Active Directory computer object using the same interface as a named user account object, the only difference is that computer objects are not shown by default in the Select dialog:

You can see the default object types selected are User, Groups, and Built-in security principal.


If you click the “Object Types” button, you can check the box for computers:
