The telephone rebuilding method allows you to talk to a Microsoft customer service representative to complete the rebuilding process. The appropriate telephone number is determined by the country/region that you chose in the Activate Server Wizard and is displayed in the Manage RDS CALs Wizard.


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 by using the telephone
  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 Telephone 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 Obtain Client License Key Pack page, use the telephone number that is displayed to call the Microsoft Clearinghouse, and give the representative your Remote Desktop license server ID and the required information for the licensing program through which you purchased your RDS CALs. The representative then processes your request to reinstall the RDS CALs, and gives you a unique ID for the RDS CALs. This unique ID is referred to as the license key pack ID.


    Retain a copy of the license key pack ID. Having this information with you facilitates communications with the Microsoft Clearinghouse should you need assistance with recovering RDS CALs.

  10. In the Manage RDS CALs Wizard, on the Obtain Client License Key Pack page, enter the license key pack ID provided by the representative into the boxes provided, and then click Next. The RDS CALs are reinstalled onto your Remote Desktop license server.

  11. 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 and 10.

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