Admin Properties / ultravnc server settings

[tech_br]

I can block user access to Admin Properties / ultravnc server settings ??


my intention is not to let expert users change UltraVNC server settings

1-
Admin properties can only be changed by a user who has write access to the ultravnc.ini in the install folder.
By default only admin users can change it.

To prevent the admin you can manual set the ultravnc.ini to read only.
To change you need to give back the write permissions.

A admin always can change the filep ermissions back to write, but out of the box it will not work.

2- Disable properties access
ultravnc.ini
[admin]
AllowProperties=1
0 = Disable "Properties" option in UltraVNC Server tray menu
1 = Enable "Properties" option in UltraVNC Server tray menu

Hi UltraVNC Forum!
I’m trying to install and configure UltraVNC 1.3.8.1 x64 Server & Viewer via PS-script, see below, to deploy om multiple computers via MS Intune. The script runs as System (Intune standard). UltraVNC Server & Viewer are installed, but the configuration, including the password for the server part, located in UltraVNC.reg are not set and the error message “You do not have sufficient priviliges to edit the default local WinVNC settings” appears. If I run the script manually as local admin, there is no problem! How to solve this?

I managed to solve this problem using Rudi De Vos answer to tech_br's problem "Admin Properties / ultravnc server settings" by adding the lines below to UltraVNC.ini, before copying it. Thanks Rudi!
