- Note the current physical address of your NIC Adapter.
- Go to Start->Settings->Control Panel and double click on Network Connections
- Right click on the NIC you want to change the MAC address and click on properties.
- Under “General” tab, click on the “Configure” button
- Click on “Advanced” tab
- Under “Property section”, you shall select “Network
Address” or “Locally Administered Address” - On the right side, under “Value”, type in the New MAC address you want to assign to your NIC without any “-“. (for example type “554433221100”)
- Goto command prompt and type in “ipconfig /all” to verify the changes. If the changes are not materialized, then use the second method. You should see something like this:
C:\Documents and Settings\Administrator>ipconfig /all
