One must have either belong to the Domain Administrators group or have been delegated extra privileges of his or her Organizational Unit by a Domain Administrator to add a workstation to the domain.

I am not sure I understand entirely. A user CANNOT add a workstation to a domain. A domain Administrator must do this. Once added, a user can log on, of course.

John: Although I doubt this is the case here, a DA can delegate a non-DA rights to add workstations and users to a particular OU, making that user an organizational unit administrator.

I was assuming a random Joe user in my post, not a special user delegated the authority to add. Thank you for the clarification.

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

The  "Add workstation to domain"  by default set to Authenticated Users on the Default Domain Controllers policy. You need to modify this and remove authenticated users. An Authenticated User (if this policy is enabled) has the rights to add 10 domain computers before getting access denied. This is due to mS-DS-MachineAccountQuota attribute in Active Directory.

If you want to allow users to add machines to the domain without being a domain admin this is also possible.

The following permissions are required to add a machine to the domain without being a domain admin...
Reset Password
Validated write to DNS host name
Validated write to service principal name
Write Account Restrictions

So the answer is you need to modify the permissions on the default domain controllers policy and remove authenticated users.

John: by default Authenticated Users can add up to 10 machines to the domain before getting access denied unless this policy has been changed to not allow this.

It's a safe assumption, but it's safer yet to not make assumptions :)

I do not have authenticated users on my servers (I do not need them). That is why I answered the way I did. I do understand what you have said. Thank you.

Also Take a look at the following link which outlines how to modify the Default Domain Policy.
