    • Set up the environment for high density robots on a Windows Server machine by installing a Remote Desktop Session Host. Then, add robot user names who can connect to the machine. It enables them to establish Remote Desktop Protocol (RDP) connection to the Windows Server machine.

    Before you begin

    Familiarize yourself with high density robots concepts. For more information, see High density robots in Unattended Robot and High density robots in RPA Hub.

    The Remote Desktop Session Host service requires a valid license.

    Ensure that you follow the hardware and software requirements. For more information, see Requirements for Unattended Robot.
