Unable to login after Win7 remote update



  • After a remote update of win7 inside my lab (25 pc) I'm no no more able to login to veyon master 4.0.3.0
    All the slave/client are connected using an admin account sharing the same user and pwd.
    A rollback to a windows recovery point before the update solve de problem: I tried only on the master PC but after the rollback I was able to login but the clients PC (also running win 7) that has been already updated to the new windows version are not reacheble (maybe for the same reason).

    Any suggegestions?
    Update to a new Veyon Version
    Some Windows configuration to check/modify
    Move to the key authentication?

    Thanks in advance
    Great job, this tool is really great!

  • Same problem for me after updates on Windows 7.

    Remove this updates do the job but it's not a long term solution.

    Thanks in advance to fix it in a future version maybe 😉
