I have two VMs on a Windows Server 2019 Standard Hyper-V host. One is Windows Server Essentials the other is a Remote Desktop Server running on Windows Server 2016 Standard. All of my user accounts are on RDS and are accessed via RDP.
I can access all of them using RDP. I cannot access my own account. It runs through the authentication process and at the second before the remote session is going to run, the screen turns blue and says "Access Declined." With an OK button below it which takes you back to the desktop where you can remote in again to any user or RDS or ESS or Hyper-V, etc.
Network and collaborate with thousands of CTOs, CISOs, and IT Pros rooting for you and your success.
