RDP Windows Login error

We have 2 terminal servers and one domain controller.   All of a sudden to day, when a user tries to log onto one of the terminal servers, they get the message:
Select6 a user to disconnect so that you may login

There are too many users logged in.

But if I get on.....   there are only 2 people logged on.

We usually have 10 - 12 people on this particular server

You're in Remote Desktop Administration mode which is 2 user max. You're not configured to be a terminal application server.

You need to go to Manage my computer, Roles, and add the Remote Desktop Service role. Add the licensing role too unless you already did.

Make sure you purchased TCALS otherwise when the 120 grace period expires, you will get kicked off

Hi Bankwest,

It sounds like your licensing has stopped working for this server and you need to run the licensing diagnostics tool, the steps described on the Technet support site.

To run the Licensing Diagnosis tool
Open Terminal Services Configuration. To open Terminal Services Configuration, click Start, point to Administrative Tools, point to Terminal Services, and then click Terminal Services Configuration.
In the left pane, click Licensing Diagnosis. Licensing Diagnosis will automatically run and try to discover license servers and identify licensing configuration problems, and then display the results.

Start -> Programs -> Administrative Tools -> Terminal Services -> Terminal Services Configuration

You can also just run tsconfig.msc

SEE MY ATTACHED SCREENSHOTS

(You can also just run licmgr.exe to go straight to terminal services license manager)

From Terminal Services Configuraton:
Licensing Diagnosis should be in the upper left corner.
Also on the right pane, examine "License Server Discovery Mode" and "Terminal Services Licensing Mode"

Make sure your license server is discovered, whether it is itself or you have the license service on a remote machine. Under licensing mode, make sure if you have "per user" checked off that on your terminal license snap-in you've installed TCALS as "per user".
If you are using "per device" make sure you added TCALS "per device". Basically, what you've configured in TS configuration has to match what you've configured under TS Licensing.

Also from terminal services configuration, double-click on RDP-TCP then the network tab. Make sure you're not limiting yourself to 2 connections.
