Remote desktop error

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:


Hope this helps. Let us know the results.
