Veyon 4.5.1 I can't open website from Master
-
Windows itself can hide the display of icons by positioning them within a hidden, windowed section of the notification area. In Windows turn on ‘Always show all icons in the notification area’ found under Taskbar settings.
You seem to have a significant level of control through Veyon though not for the ‘Run program’ and ‘Open website’ features on all except one computer.
I believe ‘Open website’ requires use of cmd. Perhaps a security setting or GPO is preventing users from accessing cmd/command prompt.

Hello,
There is a possibility that the default applications are not the same on the master and the client, and the path to the exe is also different from the master to the client -> the path recorded in the master would not be found in the clients. (i experienced both on a former version )
Good luck -

I watch this settings, but i turned on this option.

Reverse. Its working just one computer and on other 23 not.

I dont think, because i used FOG Server, and i cloned the computers. This functions (open website and run program) worked the latest veyon version.

Possibly try manually uninstalling and reinstalling Veyon using the latest version at each of the non-working client computers. If you choose to go this route after uninstalling be sure to delete all Veyon related folders (Program Files, ProgramData) and also remove all Veyon related Registry keys. After reinstalling if using key file authentication create and distribute the necessary authentication keys.

Very curious.
Some questions, are you using Microsoft Active Directory from within an on-premises domain?
Are your student computers Windows 10 Pro/Edu, if so, which update, 1909, 2004, 20H2?
Do you use key file authentication or logon authentication?

Some technical background: first you should make sure the tray icon is visible on all computers. If it's not visible, the Veyon Service for some reason is not able to run it's own worker processes within the user session. The Veyon tray icon is provided by such a worker process. Launching the "Run program" or "Open website" features also launches a (different) worker process inside the user sessions as a helper process. This worker will then start the program or open the website and this way make sure the program or browser is opened with user privileges (instead of Admin/LocalSystem privileges which the Veyon Service is running with).
On computers where the tray icon is not visible, can you please check the
VeyonServer.logfile for messages starting withWindowsCoreFunctionsand post them here? -
