Active Directory: How to prevent an OU from accidental deletion.

In Active Directory, an organizational unit (OU) is a container or a unit that can host and stores users, groups, and computers for the domain. Administrators use OUs to apply policies to users, computers, and groups.

To prevent an OU from accidental deletion,

1. log in to your domain controller as an Administrator or a user with administrative privilege.

2. Navigate to Start > Administrative Tools > Active Directory Users and Computers.

3. From the menu bar, click View and then click Advanced Features.

4. Right-click on the OU and click on Properties, then Security tab > Advanced.

5. Navigate to the Object tab and check the “Protect from accidental deletion” checkbox.
