I am looking to rdp into a remote machine, but still have that machine unlocked. The default behavior is to take the destination machine to a lock screen. I have tried remote assistance, but it does not deal with multiple monitors/displays. I simple want the normal rdp sessions to not lockout the local machine when the connection is created.
I have seen reference to tscon, but that is not present in windows 8.1 (The connection is Windows 8.1 -> 8.1 pro & Win 7 pro) It's also unclear from various examples whether that simple didn't logout the user, or actually left the local machine unlocked & visible during the session, but either way it is not available.
Regarding 3rd party tools, I have tried avaton/air-display, ultra-vnc, and teamviewer, and each have significant lag beyond that experienced in rdp.
