You can use the Recovery Manager for Active Directory reports to find out which user modified specific Active Directory objects. To provide this functionality, Recovery Manager for Active Directory requires another Quest product - Change Auditor for Active Directory. Change Auditor is designed to collect information on all critical changes occurred in Active Directory and track user and administrator activity. For more information about Change Auditor for Active Directory, please visit http:/quest.com/products/changeauditor-for-activedirectory.
To provide information on who modified particular Active Directory objects, Recovery Manager for Active Directory integrates with Change Auditor and includes the data Change Auditor provides into the reports. In order to integrate, Recovery Manager for Active Directory and Change Auditor must be installed in the same Active Directory forest.
For a list of the Change Auditor for Active Directory versions with which Recovery Manager for Active Directory can integrate to provide information about the users that modified specific AD objects, see the Release Notes for this version of Recovery Manager for Active Directory.

The Restore report provides the following information:

Important: It is currently not possible to use the Repair Wizard to bring up a Domain Controller on identical hardware using a backup from a DC which is offline due to hardware failure. Despite being on identical hardware the operating system will contain many unique parameters. Those parameters are defined during the installation of the Operating System. Repair wizard will replace the current DIT file (with transaction logs) and the registry, however replacing the registry taken from another OS (even with similar hardware) may lead to OS instability or it may not function at all. For this reason, we do not recommend using the Repair Wizard in this situation. |
To perform a complete offline restore
The Repair Wizard enables the recovery of the whole Active Directory database on a domain controller by applying a backup that was created for that domain controller.
You can use the complete offline restore to restore the entire Active Directory database from backup media without reinstalling the operating system or reconfiguring the domain controller. The restore can be performed on any domain controller that can be accessed remotely. By default, this operation restores all directory objects on the target domain controller non-authoritatively. This means that the restored data is then updated via normal replication. A non-authoritative restore is typically used to restore a domain controller that has completely failed due to hardware or software problems.
|
Important: A backup created for a given domain controller cannot be used to restore the Active Directory database to other domain controllers. |
A complete offline restore also allows you to mark individual objects for authoritative restore. However, given that the granular online restore process provides the same functionality with much less effort and overhead, it is the recommended method for restoring individual objects to Active Directory.
During the final stage of a complete offline restore, the recovered domain controller is restarted in normal operational mode. Then, Active Directory replication updates the domain controller with all changes not overridden by the authoritative restore. It is important to note that until the replication update has completed, some of the directory object data held on the recovered domain controller may be obsolete. Therefore, execution of a complete offline restore may result in additional downtime due to replication delays.
There is one other consideration to make when performing a complete offline restore. Since you cannot use the backup from the other domain controller for the restore, the restored domain controller may lose information about the directory updates that were made after it was backed up. For example, suppose that some directory objects were added or modified on the domain controller after the backup was created, but the new objects or modifications were not yet replicated to other domain controllers. In this case, when the domain controller is restored, the new objects or modifications will be lost, because they were never replicated to other domain controllers, and therefore cannot be applied to the restored domain controller.
The Repair Wizard lets you select the target domain controller and the Active Directory backup for that domain controller, and then guides you through the operation.
|
Note: You can select the domain controller where you want to restore Active Directory and then start the Repair Wizard by clicking Repair on the Action menu. As a result, the wizard only displays the backups created for that domain controller. |
In the Repair Wizard, you can use backups created by applications that store backups in Microsoft Tape Format (MTF), such as Windows Backup or Veritas Backup Exec
Active Directory restoration requires that the domain controller be restarted in Directory Services Restore Mode. At your discretion, the wizard restarts the target computer automatically or allows you to restart the target computer manually.
|
Important: You will need to log on to the target computer as an Administrator after the Repair Wizard restarts it in Directory Services Restore Mode. To do this, you must use an account whose user name and password are stored in the local security account database, known as the Security Accounts Manager (SAM). You cannot use the user name and password of the Active Directory administrator. |
To restart the computer in Directory Services Restore Mode
After the target domain controller is restarted in Directory Services Restore Mode, the wizard restores the Active Directory database from the backup.
Optionally, the wizard allows you to mark individual objects, a subtree, or the entire directory as authoritatively restored. To mark AD objects, subtree, or the entire AD database as authoritative, Recovery Manager for Active Directory uses the capabilities provided by the Ntdsutil.exe tool supplied with Microsoft Windows. However, this tool included in Windows Server 2008 or higher does not support marking the entire AD database as authoritative.
The authoritatively restored objects replace existing copies of those objects on all domain controllers and prevail for the entire domain.
After the Active Directory database is restored, the target domain controller must be restarted in normal operational mode. At your discretion, the Repair Wizard restarts the target computer automatically or allows you to restart the target computer manually. The restore operation is not completed until the target domain controller is restarted in normal operational mode.
This section provides important information you should consider when recovering Active Directory with the Repair Wizard.
The wizard allows you to restore Active Directory information on a domain controller by restoring its components from a System State backup. This restores the entire Active Directory database along with the other System State components on which Active Directory depends—SYSVOL and Registry.
The wizard offers the following two options for restoring Active Directory:
