The Protected Users security group was introduced with Windows Server 2012 R2 and continued in Windows Server 2019. This group was developed to provide better protection for high privileged accounts from credential theft attacks. Members of this group have non-configurable protection applied. In order to use the Protected Users group, PDC should be running with a minimum of Windows Server 2012 R2 and the client computers should be running with a minimum of Windows 8.1 or Windows 2012 R2.
If a member of this group logs into Windows 8.1, Windows Server 2012 R2, Windows 10, Windows Server 2016 or Windows server 2019, we can expect the following:
• Members of this group cannot use NTLM, digest authentication, or CredSSP for authentication. Plain text passwords are not cached. So, any of the devices using these protocols will fail to authenticate to the domain.
• Kerberos long-term keys not cached. For accounts in this group, the Kerberos protocol verifies authentication at each request (the TGT acquired at log on).
• Sign-in is offline. A cached verifier is not created at sign-in.
For the Protected Users group feature, it is not a must to have a domain or forest functional level run on Windows Server 2012 R2 or higher (Windows Server 2008 is the minimum as Kerberos needs to use AES). The only requirement is to run the PDC emulator FSMO role in the Windows Server 2012 R2 domain controller.
If the AD environment uses Windows Server 2012 R2 or Windows Server 2016 domain functional levels, it provides additional protections with Protected User groups, as:
• No NTLM authentication
• No DES or RC4 encryption in Kerberos pre-authentication
• No delegation using the unconstrained or constrained method
• No Kerberos TGT valid more than 4 hours
[su_note]Service accounts and computers cannot be members of the Protected Users’ security group. These accounts can be protected using different features, such as policy silos, which I will explain later in this chapter.[/su_note]
To start with, we can review the Protected Users security group using the following command:
Get-ADGroup -Identity «Protected Users»
The following screenshot shows the output for the preceding command:
We can add users to the Protected Users group using ADAC, ADUC MMC, and PowerShell. This group is located in the default Users container in AD.
In here, we are going to add the user account Adam in to the Protected Users group using the following command:
Get-ADGroup -Identity «Protected Users» | Add-ADGroupMember –Members «CN=Adam,CN=Users,DC=rebeladmin,DC=com»
The first part of the command will retrieve the group and the second part will add the user Adam to it.
After the user is added to the group, we can verify group membership using the following command:
Get-ADGroupMember -Identity «Protected Users»
The following screenshot shows the output for the preceding command:
In order to test this, we are going to use a tool called mimikatz (https://github.com/gentilkiwi/mimikatz/blob/master/README.md), which can be used to do experiments with Windows security.
I logged in to a computer as user liam , and he is not part of the Protected Users group. When I list keys from LSASS for users, I can see Liam’s NTLM hash clearly:
When I do the same thing for user adam, who is a member of the Protected Users group, I cannot see the NTLM hash stored in the LSASS memory because members in the protected group do not use NTLM and don’t save any credentials in the cache:
This marks the end of this blog post. Hope now you have better understanding how protect user groups works. If you have any questions feel free to contact me on rebeladm@live.com also follow me on twitter @rebeladm to get updates about new blog posts.

Today we will talk a bit about the organizational structure in Windows Server. Specifically, about the Active Directory Groups in the Domain. Previously we saw how to create a user in the domain controller. However, today we will go further and see how to create Groups. This allows you to group several users within a single unit. Consequently, it is easier to manage the permissions and rules assigned. For this reason, today we will see how to create Active Directory Groups in Windows Server 2019/2016.
How to create Active Directory Group in Windows Server 2019
For better administration, Windows Server classifies the groups as follows:
- Distribution groups. Used to create e-mail distribution lists
- Security groups. Implemented to assign permissions to shared resources in the domain
As for the scope of location, Windows Server classifies the groups in:
- Universal: Applies to both local and external connections
- Global: Applies to all computers and servers in the domain
- Domain local: This applies only to the local server with Windows Server 2019
Before starting to create the group it is advisable to create an organizational unit, as I show you here. The first thing you have to do is go to the Server Manager. Then, from the Tools menu please select Active Directory Users and Computer:
Then right-click on the organizational unit. Then select New>Group
A wizard will immediately be displayed to assign the group name and manage other aspects. Such as the scope and type of the group.
Finally, you can see the successfully created group:
How to add members to a group in Windows Server
There are a couple of methods to add users to a group on Windows Server. The first is through the properties of the group itself. To do this, double-click on the group and then click on the Members tab. Then click on Add.
Then enter the name of the user you want to add to the group. It is also necessary to check the name to verify the existence of the user.
Back to the previous screen you can see that the user has been added successfully. Please press OK to save the changes.
The other way to add a user to a group is through the user’s own properties. With this in mind, double-click on it and then select the Member of tab
Once again, add the name of the group and check to verify its existence:
Back to the previous window, you can see the new group added. Please click OK to save the changes.
Conclusion
At the end of the day we have seen how to create Active Directory Groups in Windows Server 2019/2016. Therefore, user management tasks are greatly facilitated. All right, that’s it for now. Stay tuned for more info on Windows Server. See you later!
