Logging - MAC Address Filtering (Deny)

I am trying to find out where I would see any MAC address that is blocked when the Deny Filter is enabled and MAC addresses are added.  I have looked in the Microsoft DHCP Service Activity Log (DhcpSrvLog-%day%) and see Event ID's 15 (A lease was denied) and 33 (Packet dropped due to NAP policy).  Am I looking in the right place for such things and if so, would it be Event ID 15 or 33 or another?

Thanks in advance.
