Hi. Windows XP Machine. Using latest Smart Security 4.X It has two Vlans. On one Vlan it is reporting this... LEVEL : Critical Warning EVENT: Detected unexpected data in protocol Source: It shows 5 ip addresses in the same Vlan (each IP on it's own line) Target: it shows the same X.X.255.255 where X is the Vlan. Protocol: UDP I have added these IP's to the trusted Zones and it still reports the Critical Warning. Is there anything else I can try. I understand that the problem could be something on that network broadcasting somethign via udp.. how do I get it to NOT report the Critical error?
