Remote desktop error

Question

I am receiving the error "the remote session was disconnected because the remote desktop client access license stored on this computer has been modified" when trying to connect to a server 2003 machine.  I am running Windows 7 but have no trouble connecting to two other server 2003 machines or XP.  It seems to be some type of conflict with this specific machine and Windows 7.  I can connect to this server from an XP machine.

Hi Russ,

First, I would suggest you to create a System Restore Point manually, so that in case, something goes wrong while performing these steps, you may always perform a System Restore and revert back.

Normally we receive this error message if the TS license in the computer is damaged or corrupt, you may need to remove it from the TS client. The license is stored in the client's registry.

1.  Click on Start

2.  In the start search box type REGEDIT and press enter.

3. In the registry editor access the following key:  HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing.

To clean the client's license cache, just delete this key and its sub keys. The next time the client connects to the server, it will obtain another license.

Registry Disclaimer:

Sometimes this problem is caused by two Windows registry entries that have become corrupted. To fix the problem, you have to use Registry Editor to delete the corrupted Registry entries.

However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

For more information about how to back up and restore the registry, follow the steps as in the KB Article: http://support.microsoft.com/kb/322756/

Hope this helps. Let us know the results.

Thanks and Regards,

I'm having the same issue. I need to connect to 3 different servers, since going to Windows 10, I can only connect to one of the servers and then I get the license error. And it too only works one time, if I disconnect from the first server I've connected to, I can't connect to any of the servers. I'm also accessing these servers from CyberArk, which then starts RDC.

Answer 3

The same for me as well. Deleting the Registry key works however the same issue on subsequent logons. Did you get any luck with this issue ?

Answer 4

Sadly, I've not had any response. Will try replacing theregistry keys from a working Win10 machine, hopefully next week. Hoping for more quiet time once our students are on break and I can work on my own machine.

Beware - after trying this "fix" we got the following error:

RemoteApp Disconnected

The remote session was disconnected because license store creation failed with access denied.

Please run remote desktop client with elevated privileges.

This even happens logged in as the domain admin.

I restored the registry settings and rebooted, will see what we need to do next to get this fixed up, but wanted to share...

Hi, 

I had the same issue but I think I got a fix for it. So once you get this error, all you need to do is to open task manager, and in the Run box (check the box for admin privilege) type the complete path to that RDP file. It would run it with admin access and It would be able to create a new entry in Registry.
