THE REMOTE SESSION WAS DISCONNECTED BECAUSE THERE ARE NO TERMINAL SERVER LICENSE SERVERS AVAILABLE

I found this issue when try to remote desktop (RDP) to the production server, Windows Server 2012.   My workaround is using mstsc /admin can RDP without any issue.

Another method, you may need to touch the Registry on the server. Refer to this article below:

PERFORMANCE MONITOR UNABLE TO ADD THESE COUNTERS

When open the Performance Monitor (PerfMon) in Windows, you may found this alert "Unable to add these counters" as below;

 In my situation, I just perform few steps and it's solved my problem.

Steps:
1. Open the command prompt (CMD) with run as Administrator.
2. Go to the path C:\Windows\System32\ 
3. Type this command lodctr /R
4. Done.
