Windows Server 2025 Remote Desktop Services - 1 User CAL

Question

Windows Server 2025 Remote Desktop Services - 1 User CAL 授權無法辨識

Answer 1

當 Windows Server 2025 報告 RDS 使用者 CAL 無法辨識時，最常見的原因是 CAL 版本與授權伺服器版本不匹配。RDS CAL 是版本鎖定的，也就是說 2025 CAL 只能安裝並由執行 Windows Server 2025 的遠端桌面授權伺服器發放。如果您嘗試將它們載入到 2019 或 2022 的授權伺服器上，它們將不會被接受。

解決方法是確保在 2025 伺服器上安裝並啟用遠端桌面授權角色，然後使用 RD 授權管理員 (licmgr.exe) 以正確的合約號碼或授權金鑰安裝 CAL 套件。安裝完成後，請確認 RD 工作階段主機已設定指向 2025 授權伺服器 (gpedit.msc > 電腦設定 > 系統管理範本 > Windows 元件 > 遠端桌面服務 > 遠端桌面工作階段主機 > 授權)。

如果 CAL 仍然無法發放，您需要聯繫 Microsoft Clearinghouse 重新驗證授權套件，因為他們可以將 CAL 重新關聯到正確的伺服器版本。

Answer 2

If you are experiencing issues with the Windows Server 2025 Remote Desktop Services (RDS) User CAL not being recognized, it is essential to ensure that the RDS CAL is compatible with the version of the Windows Server you are using. According to the compatibility guidelines, RDS CALs for Windows Server 2025 can only be used with a license server running Windows Server 2025. Additionally, ensure that the license server is properly activated and that you have the correct licensing mode configured (either Per User or Per Device).

If the CAL is still not recognized, you may want to check the RD Licensing configuration and ensure that the CALs are installed correctly on the license server. Using the RD Licensing Diagnoser tool can help identify any issues with the licensing setup.
