title: Seemless AD join with AWS AD Connector in private subnet
body: <p>I have the following network setup and try to join EC2 instances with an on-prem active directory.</p>
  <ol>
  <li>Ec2 running inside a private non-routable subnet</li>
  <li>Ad connector runs in a on-prem connected subnet</li>
  <li>the domain is dns resolvable throughout the whole VPC</li>
  </ol>
  <p>In this setup is it possible to join the ec2 instance through the AD connector without having the instance a direct connection to the on-prem AD?</p>
  <p>When the AD Connector is up and running with status active, should it show up in the on-prem directory as domain controller?</p>
  <p>Anyone experience which Windows Server versions are supported for the AD connector? Server 2019?</p>
