Event ID 19 — Remote Desktop License Server Activation

  • Article

Applies To: Windows Server 2008 R2

To install and issue Remote Desktop Services client access licenses (RDS CALs), a Remote Desktop license server must first be activated. When the license server is activated, Microsoft provides the license server with a limited-use digital certificate that validates server ownership and identity. Microsoft uses the X.509 industry standard certificate for this purpose. Using this certificate, a license server can make subsequent transactions with Microsoft.

Resolve

Check the service, and if necessary, reactivate the license server

To resolve this issue, check that the Remote Desktop Licensing service remains running and that the Remote Desktop license server continues to function properly. If the problem persists, reactivate the license server.

Check the Remote Desktop Licensing service

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

To check the Remote Desktop Licensing service:

  1. On the license server, open the Services snap-in. To open the Services snap-in, click Start, point to Administrative Tools, and then click Services.
  2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Yes.
  3. In the Services pane, right-click Remote Desktop Licensing, and then click Properties.
  4. On the General tab, ensure that Startup type is set to Automatic. If it is not, click Automatic, and then click OK.
  5. Confirm that the Status column for the Remote Desktop Licensing service displays Started.
  6. If necessary, right-click Remote Desktop Licensing, and then click Start.
  7. Confirm that the Status column for the Remote Desktop Licensing service displays Started.

Reactivate the license server

Note:  The automatic reactivation method requires Internet connectivity from the computer running the Remote Desktop Licensing Manager tool. Internet connectivity is not required from the license server itself. This method uses TCP/IP (TCP port 443) to connect directly to the Microsoft Clearinghouse. You can also reactivate the license server by using a Web browser or by using the telephone. For more information about these activation methods, see "Reactivate a Remote Desktop License Server" in the Remote Desktop Licensing Manager Help in the Windows Server 2008 R2 Technical Library (https://go.microsoft.com/fwlink/?LinkId=177764).

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

To reactivate the license server automatically:

  1. On the license server, open Remote Desktop Licensing Manager. To open Remote Desktop Licensing Manager, click Start, point to Administrative Tools, point to Remote Desktop Services, and then click Remote Desktop Licensing Manager.
  2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Yes.
  3. Ensure that the connection method for the license server is set to Automatic connection (recommended) by right-clicking the license server that you want to reactivate, and then clicking Properties. On the Connection Method tab, change the connection method if necessary, and then click OK.
  4. Right-click the license server that you want to reactivate, point to Advanced, and then click Reactivate Server. The Reactivate Server Wizard starts.
  5. On the Welcome page, click Next.
  6. On the Information Needed page, provide the requested information, including the reason for the reactivation, and then click Next.
  7. Your request to reactivate the license server is sent to the Microsoft Clearinghouse for processing, and the license server is reactivated.
  8. On the Completing the Reactivate Server Wizard page, click Finish.
