How to Find a MAC Address

Most of us are familiar with using the IPCONFIG /ALL command to display the full IP configuration, including the MAC address of each network adapter. The trouble with using this command to get the MAC address is that it displays too much information, especially if your computer has multiple NICs. Another problem is that it can only be run on the local machine - you cannot use it to get the MAC address of a remote computer or server.

That's where a little known utility, GETMAC, comes in. GETMAC has been included in every Windows build since at least Windows XP, up through Windows 7 and Windows Server 2008 R2.

The command:

GETMAC /V

will display the name and MAC (Physical Address) each local network adapter.

You can get the same information about a remote computer using the command:

GETMAC /S [ComputerName] /V

Note that you must have administrator rights on the remote machine.
