The deleted Active Directory obejcts which are in the Deleted Objects are also called Tombstones. Under Windows 2003 and Windows Server 2008 these tombstones can be restored, but during this Tombstone Reanimation, some important attributes get lost (especially references to other objects like group memberships).
In a environment with Windows Server 2008 R2 domain controllers and an according forest functional level, you can activat an additional feature: The Active Directory Recycle Bin . Deleted objects can be completely undeleted within the Deleted Object LifeTime – with all their properties.

10- Werding v2 (English version): Online data recovery for Active Directory
Download+Examples
Type: Command
Werding is a script-based tool that helps in online recovery of Active Directory data. You can use it in conjunction with ADrestore by Sysinternals ,ADRestore.NET by Guy Teverovsky  or similar tools.
Werding has two operational modes: backup mode creates a CSV/XML backup of your AD data. Restore mode reads attribute values from the backup files and writes them back to AD. This is useful when you chose to recover a deleted AD object using a tombstone restore with ADrestore. This re-animated tombstone will have lost most of its attribute values including all group memberships. Werding can restore those values and all group memberships for such an object.
