The “ask DS team” posted a blog post about “Two lines that can save your AD from a crisis”. Not a bad thing to do as it will prevent you or another admin to accidentally delete users or computer objects.

The lines they wrote protected users, computers and OUs. Did they forget about Groups?

Anyway, to also include all your groups:

# Set the "ProtectedFromAccidentalDeletion" attribute to "true" on all users,
# computers and groups in your domain where the attribute is set to "false"

Get-ADObject -filter {ObjectClass -eq "user" -or objectclass -eq "group"} -Properties ProtectedFromAccidentalDeletion | where {$_.ProtectedFromAccidentalDeletion -eq $false} | Set-ADObject -ProtectedFromAccidentalDeletion:$true


If you try to delete a user og computer object, you will get an error stating the object is protected from accidental deletion. You will have to untick the “Protect object from accidental deletion”:

What if you’d like to move the user object to a different OU? Same error as above. You must set the attribute to ‘false’.

If you have hundreds of objects in an OU you’d like to move, it’s easier to use Powershell to revert the attribute of all objects in the spesific OU:

Get-ADObject -SearchBase 'OU=OU1,dc=domain,dc=com' -filter {ObjectClass -eq "user" -or objectclass -eq "group"} -Properties ProtectedFromAccidentalDeletion | where {$_.ProtectedFromAccidentalDeletion -eq $true} | Set-ADObject -ProtectedFromAccidentalDeletion:$false


Will Gareth Bale stay with Spurs next season?
