Solution :- Important This section, method, or task contains steps that tell you how to modify the registry. 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, click the following article number to view the article in the Microsoft Knowledge Base:

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

For 16-bit RDP clients, run regedit /v. Then delete the keys under "\Software\Microsoft\MSLicensing" to clean the client's license cache. You can also delete the BIN files from \Windows\System\Regdata OR Delete the %temp% data.

If you delete the HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing subkey on a client that is running Windows Vista or a later version, later attempts to connect to a Terminal Server may fail. Also, you receive the following error message:
An Error occurred in the Licensing Protocol
To resolve this problem, right-click the Remote Desktop Connection shortcut, and then click Run as Administrator. By default, the remote desktop connection runs as a user with the lowest user permissions. By default, a restricted user does not have permission to write registry entries to HKEY_LOCAL_MACHINE. Therefore, attempts to rewrite the MSLicensing key fail. Starting Remote Desktop Connection with administrative credentials provides the permissions that are necessary to write the needed registry keys.
