Find Your MAC Address In Windows XP

Sometimes when setting your computer up on a specific network or when troubleshooting network problems you need to find your MAC address or physical address, which is a set of six pairs of letters and numbers that identifies your computer. Each network device you have such as an ethernet adapter/card or wireless adapter/card) will have a unique physical address.

Step1

Open the Windows Start Menu.

Step2

Click "Run". This will open up a small dialog box.

Step3

Type "cmd" into the dialog box and click "OK". This will open up a command prompt.

Step4

In the command prompt, type "ipconfig /all" and hit enter. This will display properties of your internet devices. Look for "physical address". It will be the only number separated by dashes instead of periods. This "physical address" is the MAC address for this network device.

Step5

Additionally, this screen also shows your IP address and the addresses of your DNS servers.
