Event ID 22 — Remote Desktop Services Client Access License (RDS CAL) Availability

Published: January 8, 2010

Applies To: Windows Server 2008 R2

red

When a client—either a user or a device—connects to a Remote Destkop Session Host server, the RD Session Host server determines if a Remote Desktop Services client access license (RDS CAL) is needed. The RD Session Host server then requests an RDS CAL from a Remote Desktop license server on behalf of the client attempting to connect to the RD Session Host server. If an appropriate RDS CAL is available from a license server, the RDS CAL is issued to the client, and the client will be able to connect to the RD Session Host server.

RDS CALs are installed onto a license server by using the Remote Desktop Licensing Manager tool.

Event Details

Product: Windows Operating System
ID: 22
Source: Microsoft-Windows-TerminalServices-Licensing
Version: 6.1
Symbolic Name: TLS_W_PRODUCTNOTINSTALL
Message: The Remote Desktop license server "%1" does not have any Remote Desktop Services client access licenses (RDS CALs) installed and registered with the Microsoft Clearinghouse for product "%2". Therefore, the Remote Desktop license server cannot issue RDS CALs of the type "%2" to the Remote Desktop Session Host server "%3". To resolve this problem, install additional RDS CALs as required.

Resolve

Purchase and install RDS CALs onto the license server

To resolve this issue, purchase and install the appropriate type of Remote Desktop Services client access licenses (RDS CALs) onto the Remote Desktop license server. For more information about RDS CALs, see "Remote Desktop Services Client Access Licenses (RDS CALs)" in the RD Licensing Manager Help in the Windows Server 2008 R2 Technical Library (http://go.microsoft.com/fwlink/?LinkId=177732).

Important:  The Remote Desktop licensing mode configured on a Remote Desktop Session Host server must match the type of RDS CALs available on the license server.

Purchase RDS CALs

To purchase RDS CALs, do one of the following, depending on your country or region:

Install RDS CALs onto the license server

Note:  The automatic RDS CAL installation 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 install RDS CALs onto the license server by using a Web browser or by the using the telephone. For more information about these installation methods, see "Install Remote Desktop Services Client Access Licenses" in the RD Licensing Manager Help in the Windows Server 2008 R2 Technical Library (http://go.microsoft.com/fwlink/?LinkId=177605).

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

To install RDS CALs 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 Remote Desktop license server is set to Automatic connection (recommended) by right-clicking the license server on which you want to install RDS CALs, 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 on which you want to install the RDS CALs, and then click Install Licenses. The Install Licenses Wizard starts.
  5. Click Next.
  6. On the License Program page, select the appropriate program through which you purchased your RDS CALs, and then click Next.
  7. The License Program that you selected on the previous page in the wizard will determine what information you will need to provide on this page. In most cases, you will have to provide either a license code or an agreement number. Consult the documentation provided when you purchased your RDS CALs.
  8. After you have entered the required information, click Next.
  9. On the Product Version and License Type page, select the appropriate product version, license type, and quantity of RDS CALs for your environment based on your RDS CAL purchase agreement, and then click Next.
  10. The Microsoft Clearinghouse is automatically contacted and processes your request. The RDS CALs are then automatically installed onto the license server.
  11. To complete the process, click Finish. The license server can now issue RDS CALs to clients that connect to an RD Session Host server.

Verify

To verify that Remote Desktop Services client access licenses (RDS CALs) are installed and available on the Remote Desktop license server, use the Remote Desktop Licensing Manager tool.

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

  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.
