RDS USERCALS 200 USERS REINSTALLATION

Question

RDS USERCALS 200 USERS REINSTALLATION NOT PLEASE SUPPORT

Answer 1

To reinstall RDS User CALs (Client Access Licenses) for 200 users, you will need to ensure that you have the appropriate licenses available and follow the correct procedures for reinstallation. Here are some general steps to consider:

1. Check License Availability: Ensure that you have the required number of User CALs available for installation.
2. Remove Existing CALs: If you are reinstalling, you may need to remove the existing CALs from the RD Licensing Manager. This can typically be done through the RD Licensing Manager console.
3. Install User CALs: Use the RD Licensing Manager to add the User CALs back into your licensing server. This usually involves entering the license key and confirming the installation.
4. Verify Installation: After installation, verify that the CALs are correctly installed and available for use.
5. Testing: Ensure that users can connect to the Remote Desktop Services without issues after the reinstallation.

If you encounter specific issues during this process, it may be helpful to consult the troubleshooting documentation related to Remote Desktop Services installations or licensing issues.

Answer 2

Hello Maharshi,

When you reinstall a Remote Desktop Services environment, the RDS CALs do not automatically restore unless the license server database is preserved. If the RDS Licensing Server or OS was reinstalled, the CAL database is reset and the 200 user CALs must be reinstalled. The supported method is to open Remote Desktop Licensing Manager (licmgr.exe), right‑click the server, and select Install Licenses using the original license pack ID or agreement number. If you no longer have those details, you must contact the Microsoft Clearinghouse by phone, where they will verify entitlement and reissue the CALs.

If you backed up the license database located in C:\Windows\System32\LServer, you can restore it before starting the Licensing service to recover the CALs. Without a backup, reinstalling via Licensing Manager or Clearinghouse is the only option. Also confirm that the RDS deployment points to the correct license server in Server Manager under Deployment Properties > RD Licensing, or via Group Policy under Remote Desktop Session Host > Licensing.

If CALs are not reinstalled, users will be blocked once the grace period expires. The immediate next step is either restoring the LServer database if available or contacting Microsoft Licensing Support to reinstall the 200 user CALs.
