MN100 and mac filtering

I have an access list of MAC addresses of my lan pc's and I have it set to
deny any others. I have the firewall turned on but I noticed this morning I
didnt have block ping commands selected so I did select it this morning.
( I was testing bandwidth forgot to set it back)
Every once in a while I see similar MAC filterings but last night I was
looking at the log and saw many entries like this, and I mean many

2004/04/14 04:55:58 MAC filtering settings blocked MAC: 000000000001
2004/04/14 04:59:58 MAC filtering settings blocked MAC: 000000000001
2004/04/14 05:01:58 MAC filtering settings blocked MAC: 000000000001
2004/04/14 05:05:58 MAC filtering settings blocked MAC: 000000000001

Also, this morning I found my windows 2000 pro box had been rebooted. I
don't know how that would of been done. I have the motherboard set to stay
off on power failure so there was no power fail.
Please tell me how they rebooted my pc? I wonder if there was a windows
critical update and would that have done it or what circumstance would
reboot a Win2000pro PC ?

Check for virus or malware on the computer. You could
also have a critical failure and the system rebooted, or
a power failure too short for shutting down the computer
but sufficient to have a CPU reset.

The MAC address: on some cards we can enter whatever MAC
address we want, or fake MAC addresses directly into IP
frames (and we can also fake the calling IP)...
