Hello @Lockard Spencer (CI/CWR21-EA) ,
Thank you for posting here.
I am sorry, the version of Windows NT is too old, so we can't find the Active Directory Client Extension for Windows NT you want.
I suggest we can use Windows server 2016/2019 instead of Windows NT if possible.
As always, if there is any question in future, we warmly welcome you to post in this forum again. We will try our best to help you.
Thank you for your understanding and support.
Best Regards,
Daisy Zhou
