UltraVNC Reverse/ Screen Locked

Postby zago123 » 2018-01-05 13:11

Hi guys,

i need help,

I'm using ultravnc on my computers, I use it in reverse mode, that is, when I'm on some problem client computer, I have a program that calls the server through the reverse vnc. the server it is in listen mode.

The problem is this, every time I open some application that needs administrator permission the vnc blocks the screen for me and I can not move.

In what options do I change this?

thanks

Cause:
UAC block applications with lower permission to send data to higher.
Workaround
1) If winvnc is started with "runas admin" you are able to control the admin apps, but still you are not able to press the UAC prompt on the secure desktop.
2) if winvnc is started as service you are able to control the admin apps and you can access the secure desktop

In most cases 1) will do as the user is in front to help the grant access to admin apps.
