Remotely Find MAC Addresses on Your Windows Network

I had to find the MAC address of a remote machine on my network this morning. Happily, WindowsXP (and above) make this easy.

They include a tool called getmac which does just that -- it gets the MAC address of any machine on the local network.

(This utility first made its appearance, it seems, as part of the Windows 2000 Resource Kit, and is available as a download from Microsoft.)

The tool couldn't be simpler to use, just open a command prompt and type:

getmac /s <computername>

It then spits back:

Physical Address Transport Name
=================== =========================================================
00-00-00-XX-XX-XX DeviceTcpip_{0AB4C22A-1EEE-AAAA-XXXX-0X0X0X0X0X0X},

There are additional switches you can use to format the output or run the command under different credentials (from the TechNet article):

/u Domain User : Runs the command with the account permissions of the user specified by User or DomainUser. The default is the permissions of the current logged on user on the computer issuing the command.

/p Password : Specifies the password of the user account that is specified in the /u parameter.

/fo { TABLE | LIST | CSV } : Specifies the format to use for the query output. Valid values are TABLE, LIST, and CSV. The default format for output is TABLE.

/nh : Suppresses column header in output. Valid when the /fo parameter is set to TABLE or CSV.

/v : Specifies that the output display verbose information.

/? : Displays help at the command prompt.
