I can't connect to AWS instance using AWS AD credentials

Question

I was following this tutorial to create an AWS managed Active Directory which also creates an EC2 instance already joined to a domain. I can connect via RDP with the local Administrator account using Remmina , but I can't connect to the instance using the "Admin" user from the AD.

I created another Windows Server 2016 instance and I joined it to a new domain, and created a Two-Way Trust Relationship.

AWS veryfies that the relationship is working correctly. I can ping and get responses from everywhere ( from instance 1 to the AD Server corp.example.com , From instance 1 to instance 2, from instance 2 to instance 1, and from instance 2 to the AD Server).

But I still can't connect to the instances using AD credentials via Remmina.

What is going on? Why can't I connect?

I still need everyone's help, please!

Answer 1

从Microsoft远程桌面版本10.2.2（1291）连接RDP时遇到了相同的问题，我降级到版本8.0.44（内部版本30030），现在可以正常工作了。
