Cannot Setup DFS namespace on EC2 instance

Question

I have an EC2 instance which I have domain joined using the AWS microsoft Active Directory. I installed the DFS namespace and DFS replication roles in server management.

But now when I go to Add new namespace I get an error saying: "Cannot connect to the domain"

When I try to do Delegate Management permissions I get a similar kind of error:

Answer 1

This was my bad, I was RDP'ed into the instance and not domain joined with it.
