I really need help right now. In AD DC one of our organizational units named "Columbus" is missing. It has Users in the unit, and now the Users and the Organizational unit is now missing. I searched for Users from Forest root, with out any luck. How do know undelete the organizational unit and/or users. Please for example.

I found the PS example, but I do not know how to filter organizational Unit.

Get-ADObject -SearchBase "CN=Deleted Objects,DC=Jones-Stuckey,DC=Local" -ldapFilter:"(msDs-lastKnownRDN=Columbus)" –IncludeDeletedObjects –Properties lastKnownParent

  • Greg Yes. I found the organizational unit and users. When I recover them, none of their Memeber of are correct. How would I restore Member of to each recovered user? – Benjamin Jones Sep 3 '13 at 19:43
  • Do you have the Recycle Bin feature enabled? – Greg Askew Sep 3 '13 at 19:44
  • You're saying that the user's group memberships are not there? – Greg Askew Sep 3 '13 at 19:46
  • You are correct. I can see users. They are disabled with no Membership except Domain USer – Benjamin Jones Sep 3 '13 at 19:49

I believe this TechNet article has all the steps you need to do a restore of your OU:


In Windows Server 2003 Active Directory and Windows Server 2008 AD DS, you could recover deleted Active Directory objects through tombstone reanimation. Introduced in Windows Server 2003, tombstone reanimation took advantage of the fact that Active Directory kept the deleted objects in the database for a period of time before physically removing them.

(Credit to the engineer that termed this "tombstone reanimation".)
