Using ADRestore tool to restore deleted objects

 Have ever encountered the following scenarios? 
  • User accounts, groups, computers, OUs or other objects in domain accidentally deleted.
  • No system state backup available for authoritative restoration.
  • No other DC's available.
  When an object is deleted from Active Directory, it isn't actually removed but
is instead marked as deleted by an internal marker called a tombstone. 
If you have valid system state backup, you can refer to the following knowledge 

base article to restore the object: 
 How to restore deleted user accounts and their group memberships in 
Active Directory 
  In case you don’t have any system state backup, you can use ADRestore 
to restore tombstoned objects. ADRestore is a command-line utility that lists 
and lets you restore deleted Windows Server 2003 AD objects. 
You can use ADRestore to restore tombstoned objects without 
performing an authoritative backup restore. You can download the utility at: 
  After you install ADRestore, you can restore an object by running 
the command ADRestore –r. ADRestore removes the 'isDeleted' TRUE attribute 
from tombstoned accounts and changes the RDN back to the previous path, 
effectively resurrecting it. 
  The -r tells ADRestore to prompt the user before restoring the AD objects
to their original location. When you run the command, 
you'll see messages similar to the following:

  • By default, users are disabled and user passwords are empty after the above method is performed. Note that if you try to bulk enable objects and some of them have passwords which do not meet complexity/length requirements, you will not be able to re-enable them. Selecting one of them will show a more verbose error message in 2003. Your option then is to change their password or lower your password policy requirements.
  •  ADRestore cannot restore the group membership for a user. Meanwhile, not all attribute data can be restored.
  •    ADRestore is the last choice and we may use this method only when valid system state backup does not exist. Furthermore, ADrestore does not aim to substitute System state backup of domain controllers. It’s highly recommended to perform regular system state backup on domain controllers.
  • Also note that you can provide simple filters based on object names. This command enumerates all objects with the string "comp" in the name (from ADRestore /?):
                      ADRestore -r comp
