This is interesting...
I winder if a recent windows security patch is responsible?

Subject: Administrator access in Windows 7

I occasionally help my mom with problems with her computer (PC running Windows), and since we live on opposite sides of the Atlantic, VNC is a godsend for this. She has a document with detailed instructions how to start a VNC server when the need arises, and how to determine her Internet-visible IP address, so that I can connect; I have configured her router so that incoming VNC connections get forwarded to her PC.

So far, so good, but when Windows XP went off support, we installed Windows 7, and then RealVNC server (free edition) no longer worked. I installed TightVNC server instead, which did. Problem solved, or so I thought.

Today, however, I connected to her PC once again, using Chicken (formerly Of The VNC) on my Mac. Everything went fine, until I tried to run the Registry Editor on her PC. Regedit caused a UAC warning to pop up, which I didn't see; on my end, everything just froze. Once mom accepted the UAC confirmation, I could see what was happening on her screen again, but I still couldn't *do* anything; my mouse clicks and keystrokes were ignored. Once she closed regedit, I could type and use the mouse once again, but when I tried running a Command Prompt as Administrator, the same thing happened: I couldn't see the UAC prompt, and I was unable to control the desktop until the elevated-privilege application was closed.

I guess I understand the security concerns behind all this, but it does make TightVNC a lot less useful for this kind of remote tech support. RDP is less nice because the local and remote users can't both see and control the desktop at the same time, so you can't walk people through scenarios or look over their shoulder to find out what they're doing wrong.

Is it possible to use TightVNC server in such a way that it will allow the remote user to run things with Administrator rights?

Many thanks,

Thomas
