WTSConnectSession

Question

I am trying to use this function to connect to a specific user session. I have tried everything and the function always fails with either ERROR_ACCESS_DENIED 5 (0x5) Access is denied or ERROR_CTX_WINSTATION_ACCESS_DENIED 7045 (0x1B85) The requested session access is denied. Even hard-coding the session ID in and the password like this

WTSConnectSession(2, 1 ,TEXT("test1"),false);

Is there a better way to start a user session than to use this function. I am trying to implement Fast User Switching and this is the last piece in the puzzle is to logon a user session. Thank you.

Answer 1

Are sure that you are connecting with username (specified by TargetLogonId parameter) in "Remote Desktop Users" group?

You can check it using

net localgroup "Remote Desktop users"

Another option is to enable security auditing and analyzing security event log. It will tells you exact root cause of ERROR_CTX_WINSTATION_ACCESS_DENIED
