In this article, I will show you how to check the AD Schema Version using Powershell Command. First, you need to log into your Active Directory Domain Controller.
If you have more than one domain controller, you should log in to the forest root domain controller.

If there is a pop-up screen from the User Account Control or UAC asking, then click Yes.
Run the command Get-ADObject (Get-ADRootDSE).schemaNamingContext -Property objectVersion.
