There is a problem with the license that enables your computer to connect to the terminal server. Contact the server administrator.

  • The remote computer disconnected the session because of an error in the licensing protocol. Please try connecting to the remote computer again or contact your server administrator.
  • The remote session was disconnected because there was an internal error in the remote computer's licensing protocol.

The licensing protocol handles the communication of licensing information between your computer and the Windows-based computer. If there is an error in the licensing protocol, your computer cannot be connected to the Windows-based computer. Try connecting to the Windows-based computer again. If you continue to receive this error message, contact the server administrator.

The remote session was disconnected because the client prematurely ended the licensing protocol. Please contact the server administrator. The license on your computer is not being presented to the Windows-based computer. Try connecting to the Windows-based computer again. If you continue to receive this error message, contact the server administrator.
The remote session was disconnected because the remote computer is not licensed to accept remote connections. Please contact the server administrator. The Windows-based computer you tried to log on to does not accept remote connections. Be sure you typed the name of the Windows-based computer correctly. If you continue to receive this error message, contact the server administrator.
The remote session was disconnected because a licensing message was incorrectly encrypted. Please contact the server administrator. A data encryption error has prevented your computer from giving its license to the terminal server. Try connecting to the Windows-based computer again. Encryption policies vary between systems and domains. If you continue to receive this error message, contact the server administrator.
The remote session was disconnected because there were network problems during the licensing protocol. Please try connecting to the remote computer again. A network error prevented your computer from passing its license to the terminal server. Try connecting to the Windows-based computer again. If you receive the same error message, be sure that your computer is connected to the network. If you are still unable to connect to the terminal server, contact the server administrator.
A licensing error occurred while the client was attempting to connect. (Licensing timed out.) Please try connecting to the remote computer again. An unspecified error prevented your computer from connecting to the terminal server. The problem could not be corrected before the time limit for sending the license to the terminal server had expired. Try connecting to the Windows-based computer again. If you receive the same error message, contact the server administrator.
The remote session was disconnected because no Terminal Server client access licenses are available for this computer. Please contact the server administrator. Either the license server cannot provide a license at this time, or your computer is using an expired license, and the terminal server cannot get a new license from the license server. It may also be that the terminal server cannot communicate with the license server and cannot give your computer a temporary license. Contact the server administrator.
