    Can you try to add another dependency to the service by running the following command at the command line (requires admin privileges): sc config VeyonService depend= tcpip/rpcss/lanmanworkstation/lsm/dnscache This adds the lanmanworkstation and dnscache services as dependencies. Also try to upgrade the clients to Veyon 4.9.8.

    Is it on the same subnet? Is Wake-on-LAN enabled on the NIC and/or BIOS?

    I believe that's the "Authentication" icon. How are you authenticating to the machines? Perhaps a missing authentication key on the client?

  • Veyon displays a special character when press "Alt+Gr"

    Hello, The same problem here. When I log in from “Remote Control,” when I enter my username and password containing @ and press the ALT+GR key, it enters that strange character. In my case, when connected remotely to the machine, nothing strange is displayed with the @, but when I try to enter it in a cmd, for example, I can see how it sends the same symbol with “?”. If you access the machines from Veyon itself with “Log in” instead of connecting to them remotely, it types and sends the @+ALT GR without any problems. I temporarily solve this by using ALT+64 in my case. For any other character, it would be necessary to find the corresponding number for that character in the ASCII table. Even so, as it affects passwords with special characters, it is tedious to work with this bug on a daily basis. If anyone finds a solution, that would be wonderful. Thanks in advance and best regards, [image: 1761051638988-error-veyon.png]
