You can discover the MAC address of an IP clients remotely.
Windows LAN
If you are on a Windows NT network or simple Windows file sharing, you can discover the MAC address from the MSDOS prompt of a Windows machine for any other Windows machine on your LAN as long as you know the hostname of the machine. (NetBIOS, NT, Windows Host)
Use the 'net view' command from the MSDOS Prompt to find a hostname, then use nbtstat -a to discover the MAC address
net view nbtstat -a <hostname>
TCP/IP LAN/WAN MAC Discovery w/o Hostname
If you send traffic to a host, such as with ICMP broadcast 'ping' you will populate the ARP Cache of your machine thus acquiring the MAC address which is part of that level of networking.
ping X.X.X.X
Wait for some replies (if host responds to ICMP)
arp -a
That shows the ARP Cache table.
