Finding a Hardware Address (Windows)
- Go to the Start menu and select Run.
- Type in winipcfg and press Enter.
- Make sure you are looking at the information for your ethernet card. The pull-down menu should show the model of your ethernet card. It should not say anything about a dial up, PPP, or AOL, adapter. If it does, switch it to your ethernet card. (If your ethernet card is not an option, it may not be properly installed.) The number displayed next to Adapter Address is your hardware address. It should not begin with 44-45.
- Go to a command window by typing cmd or command in the Run text box, available from the Start menu.
- Type ipconfig /all and press Enter.
- Make sure you are looking at the information for the ethernet adapter and not the dial up, AOL, or WAN adapter. The number listed next to Physical Address: is the hardware address. It should not begin with 44-45, nor should it be 00-03-8A-00-00-11.
Note: In Windows XP you must have the ethernet cable plugged in before you attempt to get the hardware address.
