Shaidar Posted June 27, 2004 Share Posted June 27, 2004 (edited) If you don't have an option in the properties of your NIC to specify a "Network address",here 's how you change it: Open your registry and navigate to this key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E972-E325-11CE-BFC1-08002BE10318} Under this key you'll see subkeys 0000, 0001, 0002. These are all the network devices installed on your windows. Find the one for your NIC you want (look in "driverdesc"). Create a stringvalue key called NetworkAddress, and fill in your desired macaddress. E.g. "0050042DBC12" for a mac address 00-50-04-2D-BC-12. So, you'll end up with a value which is: NetworkAddress REG_SV 0050042DBC12 Reboot and check with ipconfig /all that your macaddress is changed. Please make sure that you don't have 2 NIC's in your network now with the same MAC address .. you'll be presented with a lot of bluescreens.. If you use a MAC address of a NIC on another NIC, throw the original NIC away, or write it down somewhere that that MAX is taken ...

Shaidar Posted June 27, 2004 Author Share Posted June 27, 2004 I'm sure there's nothing wrong with changing a MAC address :huh: No, normally not, only when you end up with 2 NIC's with tha same MAC address ...

Digital Pimp Posted June 27, 2004 Share Posted June 27, 2004 There are meant to be utils out there capable of masking you MAC address i had one at one point then realised i didnt have a use for it. No idea where i got it, search with your old friend Google it'll find it eventually.

[idkfa] Posted June 27, 2004 Share Posted June 27, 2004 smac does that. You don't have to reboot after changing your MAC, disabling and reenabling the device is sufficient.

Shaidar Posted July 2, 2004 Author Share Posted July 2, 2004 Yep, actually it doesn't change your MAC .. it just let Windows believe "the network" that your card had another MAC... Deleting the registry key will get you you original MAC...

futb0l Posted July 17, 2004 Share Posted July 17, 2004 You wanna change it maybe for changing IP given by the ISP ( if you have dynamic IP ). and also... I don't think you need to reboot your computer just Enable/Disable the Network Card in Device Manager.

aladin167 Posted July 19, 2004 Share Posted July 19, 2004 Actually KLC Consulting just released another MAC Address spoofer tool called SMAC-CL. It is a command-line tool (console app) so people can now automate the MAC Address spoofing. Cool eh? http://www.klcconsulting.net/smac-cl readme file is http://www.klcconsulting.net/smac-cl/smac-cl_readme.htm Cheers, /a :cool: Link to comment https://www.neowin.net/forum/topic/183276-howto-change-your-nics-mac-under-2kxp/#findComment-2514359 Share on other sites More sharing options...
