06 - Windows Server 2012 Create User Group and Delete OU (Video in Khmer)

Hello my friend! Today I show you step-by-step how to Create User Security Group and Delete Protected OU on Windows Server 2012 R2 inside VMware! Group is used for managing user permissions in Active Directory. Also, many beginners get stuck when trying to delete an OU folder! Very easy to follow with video tutorial in Khmer! Let's get started!

💡 Tip: In video tutorial, I create OU named Students, create user sok.sao, create Security Group IT-Staff to add user into group, and show how to delete protected OU!

Step 1: Create Security Group & Add User to Group

1. Open Server Manager > Tools > Active Directory Users and Computers (dsa.msc).
2. Right-click your target OU or Domain > select New > click Group.
3. Enter Group name (example: IT-Staff or Sales-Group).
4. Select Group scope: Global and Group type: Security > click OK.
5. Add User to Group: Right-click your new group > select Properties > click Members tab > click Add... > type user name (example: sok.sao) > click Check Names > click OK > click Apply.

💡 Tip: Always assign folder permissions to Security Groups, NOT individual users! When new employee joins department, just add user to group and user automatically gets all permissions!

Step 2: Delete Protected Organizational Unit (OU)

When you try to right-click and delete an OU, Windows will block deletion because accidental deletion protection is enabled! Follow steps below to remove protection and delete OU:

1. In Active Directory Users and Computers, click View menu at top bar > check Advanced Features.
2. Right-click the OU you want to delete (example: Students) > select Properties.
3. Click Object tab at top.
4. Uncheck Protect object from accidental deletion > click Apply and OK.
5. Now right-click the OU again > select Delete > click Yes to confirm!

💡 Tip: If you cannot see Object tab in OU properties, make sure you enable View > Advanced Features first!
