Deleted AD Objects and a Tombstone Reanimation Tool
Deleting AD Objects and a Tombstone Reanimation Tool
In my Active Directory Recovery Planning session, I talked about a free tool which will allow you to easily ‘undelete’ an object in Active Directory. This process is called Tombstone reanimation and Quest makes a free tool that will allow you to do this without having to script something.

Here are a couple of things to note:
- You need Windows 2003 Server to do this: Only Windows 2003 exposes the APIs to allow you to officially do this. All you need is one W2K3 DC in the environment.
- Not all object attributes are restored: When you delete something in AD, the object is gutted of the majority of its attributes with only a few key identifying attributes left. Therefore, when you undelete / reanimate a tomb-stoned objected, only these attributes will be restored.
If you do not have Windows 2003 or need all attributes to be restored, your only option is to restore from some sort of backup either through an authoritative restore or through a 3rd party tool.
