Solution Change the MAC address in Windows Go to Start -> Control Panel. Double click on Network Connections (inside Network and Internet Connections category in Windows XP). The, right click on the active network connection with network adapter that you want to change the MAC address (normally Local Area Network or Wireless Network Connection) and click on Properties. Above steps work in Windows XP, Windows 2000 and Windows Server 2003. For Windows Vista, access to NIC’s properties is from Control Panel -> Network and Internet -> Network and Sharing Center -> Manage Network Connections. Alternatively, if you already know which network adapter that’s responsible for your network or Internet connection, go to Device Manager and open the properties dialog by double click on the NIC itself. In the General tab, click on the Configure button. Click on Advanced tab. In the Property section, select and highlight Network Address or Locally Administered Address. To the right, “Not Present” radio button is by default selected as value. Change the value by clicking on radio button for Value:, and then type in a new MAC address to assign to the NIC. Change MAC Address of Network Adapter The MAC address consists of 6 pairs of numbers (0 – 9) and characters (A – F) combination. For example, 88-17-E8-90-E2-0A. When entering the new MAC value, omit the dash (-), for example 8817E890E20A. Click OK when done. To verify the change of MAC address, go to command prompt, then type in one of the following commands: ipconfig /all net config rdr Reboot the computer if successful to make the change effective. Note: To restore or reset back to original default MAC address, simply set back the option to “Not Present”. Change the MAC Address of NIC in Windows via Registry Open a command prompt. Type the following command and hit Enter. ipconfig /all Record down the Description and the Physical Address (is MAC address) of the active network connection (discard those with Media Disconnected state). Get MAC Address for Network Card For example, in figure above, Description is Intel(R) Wireless WiFi Link 4965AGN and MAC address is in the format of 00-XX-XX-XX-XX-XX. In the command prompt also, type the following command and hit Enter. net config rdr Record down the GUID for the MAC address for the active connection’s NIC which MAC address to be changed. The GUID is contained within the { and } brackets right in front of the MAC address as shown in figure below. GUID for the NIC Type regedt32 or regedit in Start -> Run box or in Start Search for Windows Vista. Note: for Windows NT 4.0 and Windows 2000, regedt32 must be used. Navigate to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318} Expand the {4D36E972-E325-11CE-BFC1-08002BE10318} tree, and there will be more sub-keys in the form of 0000, 0001, 0002 and so on. Go through each sub-key starting from 0000, look for subkey that has DriverDesc value data that matches NIC description copied from step above, that want its MAC address to be changed. In most cases, it will be similar to the network adapter card name. To verify that the subkey found is indeed a correct one, check the value of the NetCfgInstanceId, which should have the same value with the NIC’s GUID taken from step above. Once a sub-key is matched to the network interface card that MAC address want to be spoofed, select and highlight the subkey. Right click on the sub-key (for example, 0000), then select New -> String Value. Name the new value name as NetworkAddress. Note: If NetworkAddress REG_SZ registry key is already existed in the right pane, skip this step. The double click on NetworkAddress and enter a new MAC address as its value data. Change and Spoof MAC Address in Registry Note that the 12-digit MAC address in hexadecimal format, and should be entered without any dash (-). For example, 1A2B3C4D5E6F. Reboot the system to make the new MAC address effective. Alternatively, if you don’t want to restart the system, try to disable and then re-enable the network adapter in Device Manager. To verify the change of MAC address, go to command prompt, then type in one of the following commands: ipconfig /all net config rdr Note: To restore or reset back to true original hardware burned-in MAC address, remove the NetworkAddress registry key that is been added.
