Like the backup process, an important part of restoring Active Directory data is performing the preliminary tasks. Before you can restore Active Directory, you must perform the following tasks:

Ensure that you can access all locations that require the restoration of files. Ensure that the appropriate device for the storage medium containing the data to be restored is attached to a computer on the network and is turned on. Ensure that the medium containing the data to be restored is loaded in the device.

To restore the system state data on a domain controller, you must first start your com puter in a special safe mode called directory services restore mode. This allows you to restore the Sysvol directory and Active Directory directory services database. You can only restore system state data on a local computer. You cannot restore the system state data on a remote computer. However, you can restore backed up system state data to an alternate location a folder you designate. By restoring to an alternate location, you preserve the file and folder structure of the backed up data all folders and subfolders appear in the alter nate folder you specify.

If you restore the system state data and you do not designate an alternate location for the restored data, Backup will erase the system state data that is currently on your computer and replace it with the system state data you are restoring. Also, if you restore the system state data to an alternate location, only the registry files, Sysvol directory files, Cluster database information files (if applicable) and system boot files are restored to the alternate location. The Active Directory database, Certificate Services database (if applicable), and COM+ Class Regis tration database are not restored if you designate an alternate location.

To nonauthoritatively restore Active Directory, complete the following steps: 1. Restart the computer. 2. During the phase of startup where the operating system is normally selected, press F8. 3. On the Windows Advanced Options Menu, select Directory Services Restore Mode and press Enter. This ensures that the domain controller is offline and is not con nected to the network. 4. At the Please Select The Operating System To Start prompt, select the appropriate Microsoft Windows Server 2003 operating system and press Enter. 5. Log on to your domain as Administrator.

Note When you restart the computer in directory services restore mode, you must log on as an Administrator by using a valid Security Accounts Manager (SAM) account name and password, not the Active Directory Administrator s name and password. This is because Active Directory is offline, and account verification cannot occur. Rather, the SAM accounts database is used to control access to Active Directory while it is offline. You specified this password when you set up Active Directory.
