I have TightVNC Server (v. 2.7.10) running on my computer (Windows 8.1 Professional). When I am physically at the computer, others can see my screen using a VNC client. However, when I RDP into my computer, other users cannot view my session; they only see the Windows lock screen.

How can I enable other users to see my current RDP session using TightVNC?

  • you use windows or linux? because at an old fedora I remember there where a screen saver and lock screen option – Quijote Shin Jul 17 '14 at 19:11
  • @QuijoteShin Would I be seeing the Windows lock screen on Linux? :) Updated. – Zev Spitz Jul 17 '14 at 19:14
  • @QuijoteShin Users are running Windows, if that matters. – Zev Spitz Jul 17 '14 at 19:28

VNC and RDP are different protocols. VNC is screen sharing, with the option of using a client's input (i.e. mouse, keyboard, etc) on the server's screen, with the server's controls still active. Remote Desktop was made for administering the computer, which started out with NT4's Terminal Services. It was part of what made Windows a multi-user environment, as each user has their own session.

When you RDP, it locks out the console on Consumer versions of Windows. For the Server editions, it does not kick off whoever is at the "console". You can over ride this by using the /admin (used to be /console) command when running mstsc.exe.

If you are using VNC, you are seeing the console's screen. If you are using RDP, you are connecting to a session. In the case of Windows Professional editions (not the servers!), you are only allowed one concurrent connection, so it locks the console's session when someone connects. There is no way around it.

  • Am I correct in assuming that even using the Server edition, I would still not be able to connect to a running RDP session via a VNC server running in that session, as VNC only exposes the console? (I know I can connect to an existing session on the Server editions using RDP.) – Zev Spitz Jul 28 '14 at 21:11
  • You are correct. They connect differently, in the rdp brings a session to you, while vnc shares the current active screen – Canadian Luke Jul 28 '14 at 22:34

Im not sure if it will work, but try to run the TightVNC standalone server from your RDP, don't run the TightVNC service (I'm guessing, that with the default install, you chose to have the service running).
