Ever got in a situation where you as AD domain admin were blocked from
Or did you ever receive an “Access denied” when you tried to delete items
from AD, even with full admin rights?
Then you better check if AD has the “protect from accidental deletion”
activated on the object, container or OU…
In case you want to check a larger collection of items for this setting, it
quickly becomes complicated.
This article helps you to get an overview by using Powershell, and an export
of the impacted items to a CSV file.
As explained by : James ONeill (Windows Server 2008 Protection from Accidental Deletion)
“The functionality to prevent accidental deletion is not based on a new attribute in Active Directory. It is enabled by ticking a check box on the Object tab of the particular object you wish to protect. The Object tab is only visible when the Advanced Features option is selected from the View menu of Active Directory Users and Computers. When the tick box is checked the permissions on the object are changed. A “Deny” permission is created which stops deletion of the object. “
This script finds all AD objects protected from accidental deletions.

on a DC.
- List Protect object from accidental deletion setting in AD (full version)
- List Protect object from accidental deletion setting in AD (light version)
