VNC'ing into a users RDP session

hada79 · Post by **hada79** » 2010-12-10 16:25

I have a user who works from home, and RDP's into her computer at work. If she calls and we have to VNC into her machine, we just see the locked screen, and not her actual RDP session. Is there a way to fix this?

without shadow remote desktop is not (yet) possible.
next major release of uvnc 2.0.0 should allow from vncviewer to choice wish RDP session to connect to remote.
RDP0 (system logon)
RDP1 log on user1
RDP2 log on user2

------------------------
tested successful myself
if your are at office with your vncviewer
ask to lady to disconnect from their computer
and you connect to their office computer.
add shorcut on their desktop or make in their startup group
(this run only while user is logged)
winvnc.exe -multi -run
ask the lady to connect remote desktop again to their office
then your vncviewer can connect to their current RDP1 session
5900 = RDP0 session locked screen console
5901 = RDP1 session of the lady logged on
vncviewer hostname:5901

hope this is clear and help

I've just found another way to get it work.
At the Console of the PC which you want to connect to may not be any user logged on!

Install VNC as a service and run the service with the same user which you use to connect via RDP.
Now, if the RDP connection is active, connect via VNC as you do usually. You'll automatically connect
to the active RDP session.

A problem is, that the RDP session may not be run in fullscreen (seamless) mode.
If you run it in fullscreen, you won't get a screen on VNC.

Sorry for my bad english, i'm not a native speaker.

This only works for XP it seems...I can't get this to be true in Windows 7. Anyone have any ideas?

Hmmm apparently I spoke too soon. For anyone seeing this behavior, we had to write a batch file that "net stops" the service and "taskkill"s winvnc.exe then restarts only one instance. Just using taskkill won't work because the service was started using NT AUTH and it will fail with an "Access Denied" message. It was constantly showing us the local image via VNC because we were connecting to the still-running service originally.

Hope that helps!

How do i apply the -multi -run switch? thanks.

Post by **Rudi De Vos** » 2021-02-07 12:59

winvnc.exe -multi -run
-multi: allow to run multiple instances of winvnc

This has nothing todo with RDP, ir just skip the "is already running" check.
