arp -a (In a windows nt based system cmd). As you see it shows my gateway only because the CAM/ARP table is being kept on the router. If you had a peer-to-peer network etc, your arp table would be larger.

Code:

C:\Documents and Settings\User>arp -a

Interface: 192.168.0.33 --- 0x2
  Internet Address      Physical Address      Type
  192.168.0.1           00-16-b6-1c-92-ca     dynamic

Use a tool to scan the local subnet and discover any hosts alive (or unprotected, computers running a software firewall will not respond to a regular ping). If arp doesn't show you the mac:

nbtstat -a <hostname or ip> (In a windows nt based system cmd)

Code:

C:\Documents and Settings\User>nbtstat -a caboose

Nvidia nForce Networking Controller:
Node IpAddress: [192.168.0.33] Scope Id: []

           NetBIOS Remote Machine Name Table

       Name               Type         Status
    ---------------------------------------------
    CABOOSE        <00>  UNIQUE      Registered
    WORKGROUP      <00>  GROUP       Registered
    CABOOSE        <20>  UNIQUE      Registered
    WORKGROUP      <1E>  GROUP       Registered
    WORKGROUP      <1D>  UNIQUE      Registered
    ..__MSBROWSE__.<01>  GROUP       Registered

    MAC Address = 00-E0-18-F1-84-84

Voila, my file server "caboose" is revealed
