; I don't really know whether this is correct but I have tried and found
that the MAC address can be changed in Win2k by issuing this command :
arp -s ip-of-the-computer mac-address

though it might be wrong..

Subject: [PEN-TEST] Changing MAC address on Win2k


I recently read in Pen-Test that the MAC could be changed in Win2k. I have
looked on the web for info, and in the archives at Security Focus but can
not find any "How To" information. Nothing on my system offers any obvious
opportunity either.

So, can anyone tell my how to change the MAC on Win2k.

This has to do with better anonymity while doing Pen-Tests. It is nice to
hop through proxies, but my MAC is always there to ID me. Specifically, I
working in a multi-site company, and their ID (they tell me) is blocking my
work based on MAC. Changing IP does not help.

Thanks Much,
Parth
