The remote desktop session shadowing setting of Windows Server 2019 is a function that allows two people to share the screen of the remote desktop destination from a terminal such as Windows 10. To enable it, change the “File and Printer Sharing Settings” in the Network and Sharing Center and the “Set rules for remote control of Remote Desktop Services user sessions” item in Group Policy on the Windows Server 2019 side.
As a usage scene that recommends session shadowing, when building or changing settings of Windows Server, there are cases where multiple people want to see the same screen and check if there are any mistakes before setting. The demand for working remotely is increasing. We recommend that you use it as needed.
