Issue: "No Remote Desktop License Servers available" error message in Windows Server 2012

Solutions:


This information applies to Windows Server 2012. There is an alternative workaround for this issue.

The first step in troubleshooting the issue should be to run the RD Licensing Diagnoser tool from Server Manager. This tool checks the existing Remote Desktop licensing configuration for problems and provides troubleshooting suggestions for any that it finds. If the RD Licensing Diagnoser reports the correct licensing information and finds no problems, the issue may be caused by an apparent bug in Windows Server 2012 in which the RDSH server fails to contact the licensing server after the 120-day licensing grace period expires.

If the licensing configuration appears to be correct and the RD Licensing Diagnoser reports no problems, please perform the following steps:

  1. Open Registry Editor (regedit).
  2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM. Export this registry key to a file before making any changes.
  3. Locate the GracePeriod key and either delete or rename it. It may be necessary to take ownership of the key and/or modify its permissions first.
  4. Reboot the RDSH server. You should now be able to successfully connect to it.
