Question : Deny Access based on MAC Address

I want to deny access to certain MAC Addresses on my Network.  However, I do not want to find and import all 500 computers' physical addresses as it will take a long time.  Is there anyway to just deny a couple MAC Addresses in the proxy server or through ISA Management?

 Thanks for your help

Answer : Deny Access based on MAC Address

3COM managed switches can do what you are asking...
I suppose Cisco managed switches should also be able to do the same...
I do not know about other brands, but for me, it to show you that it is possible...
