Check into using the "nmap" network-scanning tool.  Its -O option tries to 
figure out the OS, and after scanning your network with it you may find 
that your arp cache ("arp -a") includes the MAC addresses of all the 
machines on your LAN.

I've also found it handy to extract port/MAC mappings from my network's 
smart switch.  The "arping" command may be helpful too.
