No Remote Desktop Client Access Licenses Available

Here is a fix to the following error message with Remote Desktop Connection when you try to connect to a machine from Windows 7: “Remote session was disconnected because there are no Remote Desktop client access licenses available for this computer. Please contact the server administrator“

The solution is delete the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing

Try connecting in again. If it doesn’t work and you get the following error message: “The remote computer disconnected the session because of an error in the licensing protocol“;

Then all you need to do is Right-Click on the Remote Desktop Connection icon and select “Run as Administrator“.
