 * This event handler schedules the daily NETBIOS discovery.
 * It is executed after the 4th device fast discovery (~2m since start)
 * in order to not overload the system.
 * After that it is executed for every discovery cycle, considering that
 * the scanner autonomously skips already scanned devices.
 * The goal is to scan every device daily - the assumption is that the agents
 * reboots every day
