A. Each network card has a media access control (MAC) address that machines on local subnets use to talk to each other. These MAC addresses are usually burned into the units as part of the manufacturing process, but some network adapter cards have the ability to change the MAC address through software. If your network adapter card and driver support this feature, Windows 2000 can change it via its standard interface:

  1. From the Start menu, select Settings, Network and Dial-Up Connections, right-click the LAN instance that uses the network adapter card you want to modify, and select Properties.
  2. In the "Connect using:" section, under the name of the network adapter card, click Configure.
  3. Select the Advanced tab.
  4. Select Locally Administered Address.
  5. Type the new MAC address in the Value section.
  6. Click OK.

If "Locally Administered Address" isn't available as an option, your network adapter card or driver doesn't support MAC address alteration.
