I have recently setup a Windows Server 2012 R2 VM with Remote Desktop Services with the goal of allowing certain colleagues to access remote apps from home. I've followed install and configuration instructions via Technet and everything seems to be running as expected with one major exception. When I go to Server Manager > Remote Desktop Services > Collections > Collection > Properties > User Groups and try to add a group from the same domain that the server is joined to I get this error.
"The security identifier could not be resolved. Ensure that a two-way trust exists for the domain of the selected users.
Exception: The network path could not be found."
This is puzzling to me since the User Group I'm trying to add and the server that Remote Desktop Services is installed on are both in the same domain.
Any help with this would be greatly appreciated as people are waiting on this to be able to access specific programs from home or when mobile.
