Hello:

I request change my ethernet address in my network card (00-50-ba-46-69-20 for sample). I am working in Windows NT 4.0 and Windows Millenium. If you know how make it, please contact me. I worked with different tools, but i have not good results.

hate to brust your bubble, but, the number
is hardcoded into the card. what you can
do is spoof it at the OS level -- harder
in proprietry OSes.

the higher networking protocols query the driver
, so, imho, the best way to do it, is to make
the driver return the wrong address.

but be warned, MACs are as unique as IPs, so
if you spoof them, you might not receive the
incoming packets destined to the "fake" MAC.
i don't know much about this level of networking,
but if you wanna do this in a LAN, then the spoofing
might work perfectly.

Good luck

Isn't the MAC address added to the ethernet packet by the NIC?
That's the impression I've got after reading various documents -
I might be wrong, though. If it is, I can't see how you can be able to
fake the MAC address - unless you have a leet card that can be flashed .

Linux as a nice easy mac command line ! but I hate linux so..

I have a 3COM card in my Win2K Sp1 machine and can put in a valid mac address in the 'advanced' section driver manager setup of the NIC next to media type and flow control bla blah.

This is a nice new feature of Win2K (like Linux )

Also I have a notebook with PCMCIA card with win 98SE and this too has an option to set a mac address to the NIC. This is part of the PCMCIA driver and is not set by Win98SE.

I DL the commview 2.5 and this has a nice database of valid mac addresses to choose from

I change my mac's regularly but I think my IP address gets me f*cked anyway ! , unless I play with the server
