Reboot the computer. Make sure the Active Directory service has started successfully, and the
restored object becomes available.
Another way to restore accidentally deleted object is by using tombstones. In AD, any deleted object
is retained for a period of time (called tombstone lifetime, as discussed above). This period is, by
default, at least 60 days. That means that any object, even though deleted from AD, will remain in its
database for at least 60 days before it will be finally erased.
Using this method, the backups are not used, and AD remains available during the recovery – there is
no need to reboot a domain controller. There are several tools that perform such recovery; many of
them are available for free. For example, a command line tool from Windows Sysinternals called
adrestore can browse and restore deleted objects. Another example is a freeware tool from MVP Guy
Teverovsky called ADRestore.NET. This tool has a graphical user interface and may be easier to use.
For more information, please refer to the documentation supplied with the appropriate tools.
