The automatic rebuilding 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.


Rebuilding the RD Licensing database deletes any RDS CALs that are currently installed on the license server. After the RD Licensing database is rebuilt, you must reinstall your RDS CALs onto the license server. Therefore, before you rebuild the RD Licensing database on a license server, ensure that you have your RDS CAL purchase agreement documentation available.

Membership in the local Administrators group, or equivalent, on the RD Licensing server that you plan to configure, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at

To rebuild the RD Licensing database 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. Verify 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 rebuild the RD Licensing database, and then clicking Properties. On the Connection Method tab, change the connection method if necessary, and then click OK.

  3. Select the license server whose RD Licensing database you want to rebuild, and then on the Action menu, click Manage RDS CALs.

  4. On the Welcome to the Manage RDS CALs Wizard page, click Next.

  5. On the Action Selection page, click Rebuild the license server database.

  6. Select a reason for rebuilding the RD Licensing database, and then click Next.

  7. On the Confirm Deletion of RDS CALs page, select the Confirm deletion of RDS CALs currently installed on this license server check box, and then click Next.

  8. After the contents of the RD Licensing database have been deleted, on the Reinstalling RDS CALs page, click Next.


    You can only reinstall one set (or pack) of RDS CALs at a time. After you have reinstalled the first set of RDS CALs, the wizard asks you if you want to reinstall another set of RDS CALs. You are asked this after each set of RDS CALs is reinstalled.

  9. On the License Program page, select the appropriate program through which you purchased your RDS CALs, and then click Next.

  10. The License Program that you selected on the previous page in the wizard determines what information you need to provide on this page. In most cases, you must provide either a license code or an agreement number. Consult the documentation provided when you purchased your RDS CALs.

  11. After you have entered the required information, click Next.

  12. 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.

  13. The Microsoft Clearinghouse is automatically contacted and processes your request. The RDS CALs are then automatically reinstalled onto the license server.

  14. To reinstall another set of RDS CALs, on the Reinstalling Additional RDS CALs page, click Continue reinstalling additional RDS CALs, and then click Next. Repeat steps 9 through 13.

    To finish rebuilding the RD Licensing database, click Finish rebuilding the RD Licensing database, click Next, and then click Finish.
