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.
