I am troubleshooting a PC that is flooding our switch with directed broadcasts. I think I have cover everything but since it is still happening obviously I have not. Can you tell me why a PC would send out directed broadcasts? in other words what is the purpose of them? The PC's IP address is set to 10.66.6.40 /24 and it is flooding broadcasts to 10.66.6.255, what can it be trying to do?
