Windows Server 2012 can be a little disconcerting due to the new look and layout.
Such was the case for a request of a 2012 server with Remote Desktop Services enabled. I installed the OS and added it to AD. I installed the requested applications and then I went through the wizard and installed the “Remote Desktop Session Host.”
I didn’t need the license server installed as I have a couple already in place.
When it came time to configure verify the setup; I went to Administrative Tools and looked at Remote Desktop Services and only found “RD Licensing Diagnoser”
Ok? Where do I configure the license servers? Oh wait! the Dashboard. I looked under that and found the same thing.
I reinstalled the role and found nothing changed.
I did get the warning about licenses and so I ran the diagnoser to see what was wrong. Two license servers were found but the problem was the missing license server had the licenses for 2012.
Time became an issue and I literally had the user panicking to use the server so I needed a quick resolution as this system was a short term “crash and burn” setup.
I decided to add the missing entry via the registry and reboot.
The license server list can be found here:
HKLM\SOFTWARE\Wow6432Node\Policies\Microsoft\Windows NT\Terminal Services
The entry you need to modify is : LicenseServers
I added the missing license server to the list and rebooted.
The warning message about licenses went away and I verified multiple users could access the server.
Time to crack open the 2012 books and papers!

Similar situation. Added the missing server, but after reboot it reverts back to the original state. Which has two listings that are no longer valid. What gives?
