There is a known issue when attempting to perform remote shadowing on a windows host.
You can use this procedure as a workaround :
– Set the group policy to allow Remote Control without user consent ,
– Then you can use the following batch file to shadow or remote control a session:
set /p session=”Enter the Session ID to shadow:”
mstsc.exe /shadow:%session% /control /noConsentPrompt /noConsentPrompt
Different method integrated in RDPlus :
Add the following line : sessionsmanager-showconsentprompt=no to the [Security] section of the appcontrol.ini file located in C:\Program Files (x86)\RDPlus\UserDesktop\files.
