Important: As of April 8, 2014, Microsoft no longer supports Windows XP with security updates. To ensure the highest security standards, the UITS Support Center no longer registers Windows XP devices to the IU network. UITS strongly recommends that you look into the options for replacing or upgrading your Windows XP computers for full compatibility with IU systems. See About end of life for Windows XP.

In Windows XP, to view the MAC address of your network adapter(s):

  1. From the Start menu, select Run... .

  2. In the "Open:" field, enter cmd .

  3. At the command prompt that appears, enter: getmac

    The MAC address for all installed network adapters will be displayed in hexadecimal format.

Note: MAC addresses contain only the letters A-E in combination with numbers. Any other character aside from A-E is a number.
