    bjarneabraham , You can contact support and ask them to request AATP's service engineering to disable netbios resolution completely from the backed for your workspace (provide your tenant id and workspace id).

    This will prevent the sensors from even trying to do resolution over netbios, and since they won't even try, after some time the health alert will also go away...

    But if at some point you will change your mind and want to bring netbios back, you will need to contact them again to turn it back on.
