因為尚未準備好樹系以安裝目前版本的 Windows Server，所以無法繼續 Active Directory 輕量型目錄服務安裝精靈。請使用 Adprep 命令列工具來準備樹系及網域。請參閱 Active Directory 輕量型目錄服務說明，以取得使用 Adprep 的詳細資訊。

The Active Directory Lightweight Directory Services Installation Wizard cannot continue because the forest is not prepared for installing the current version of Windows Server. Use the Adprep command-line tool to prepare both the forest and the domain. For more information about using the Adprep, see Active Directory Lightweight Directory Services Help.
