You mean you can't login into Veyon Master when starting it? Are you using a regular AD or Entra ID?

Hello, same problem here. I installed a new classroom with 18 new windows 11 computers. I connected 3 of them with a wifi card, and I can't see these 3 in veyon master.

When i try to use "Computer containers or UOs", only a few UOs works as expected. Most of the time, "Parent UO" (from the veyon master computer) is displayed with every computers of children UOs :

"PEDAGO.lan/Ordinateurs/PC_EDS/CDI/CDI65" displays "PEDAGO.lan/Ordinateurs/PC_EDS/CDI/" computers
"PEDAGO.lan/Ordinateurs/PC_EDS/CDI/CDI65/CDI65-Eleves" displays "PEDAGO.lan/Ordinateurs/PC_EDS/CDI/" computers
"PEDAGO.lan/Ordinateurs/PC_EDS/CDF43/221" displays "PEDAGO.lan/Ordinateurs/PC_EDS/CDF43/" computers

It works well for some UO, for example :
"PEDAGO.lan/Ordinateurs/PC_EDS/CDF43/211"
"PEDAGO.lan/Ordinateurs/PC_EDS/CDF43/212"
"PEDAGO.lan/Ordinateurs/PC_EDS/NDBN-BAT-E/E201"

Also, I don't understand why I can't filter computer groups with "(objectClass=organisationUnit)" ??

@Hotdog-mann said in How do i make a thing to see people screens because my employees need to be monitored Please and thank you:

I need to be able to lock screens and view them anytime with there computers

@timoteomeireles where you ever able to get this fixed ?

Since 4.8.3 it work again 🙂

I'm actually very comfortable with veyon, so I wanted to know why the PC appears in red (authentication failed or access denied).

From what I see and can perceive, Veyon is used more in Windows than Linux (Ubuntu, Debian) in classrooms and not Linux in classrooms.
