As a system administrator, I’ve been in many situations that I needed to write down the MAC-address of a remote PC. For example to boot the PC with Wake-On-LAN in the near future.
There are several ways to get the MAC address of a computer. Below are the two methods I mostly use. There are probably many more.
- DHCP. If you’re in an Active Directory domain with DHCP enabled, you can find all computers that have been online in the last 7 days. For every computer, you can find the MAC address in the column “Unique ID”
- getmac command. When you start a command prompt, you can get a computers’ MAC address by typing getmac /s %system name%. For example, getmac /s PC09 . Note: the computer has to be turned on.
Thanks for this. I needed to wake up a computer remotely whose MAC address I hadn’t previously recorded. After getting the MAC from the DHCP records (Start > Administrative Tools > DHCP) on our Win 2k3 server, I was able to wake up the other machine with WakeMeOnLan no problem. Thanks again!
