UAC issue

Post by jbasha »

Hi All,

I have been trying to setup a reverse connection using repeater for Uvnc and i am able make it work except for below scenario.

i am getting a red box with a message like "UltraVNC running as application doesnt have permission to access UAC protected windows"

Scenario in which this issue happening:-
- i could able to do anything if the desktop is already logged in by user
- i get this error only when the windows login screen /switch user screen comes up.

I tried all possible options provided in the forum, below are the steps i carried without any success
- disable UAC ( "Change User Account Control settings." with "Never notify"
- I am running the winvnc as a service but still same issue

my VNC server running i windows embedded PC.

This is only possible running as service, else you can only viewer your own desktop.
The logon /switch desktop is a secure desktop.

Unless a service behave different on a embedded PC is should work.
if you net start uvnc_service -> Running ?
Running as system ?
