This 0.0.0.0 could result from having multiple nic's in your pc. If you have a PPP connector you would receive a MAC address from that to, but when not connected this would be 0 I'm not compleetly sure of this but a PPP dial adapter is a nic to. And it could be wrongly set to the first nic in the binding. What I wanna say is that you would need to itterate trough the list of all nic's and verify which mac address you want to use. 2 or 3 nic's per pc are not uncommon. For example . 1x NIC 1x PPP modem dial 1x PPPoE ADSL modem If you wanna verify just type ipconfig /ALL in a dos window in NT/2K/XP, the result is a complete list of all adapters AND MAC address. Type winipcfg in W9X, you get a form where you can chose from the multiple nic's and see there MAC address.

A MAC address is usually a lot more stable then a HD serial number. I wasn't aware though that a spoof utility was out there. Looks like the code will need to dig a little deeper and get the actual hardware address. BTW I'm not sure why that code I sent you returned 0.0.0.0. did the same thing here on Win98SE. It's never failed before, but then it's been a few years since I used it. I looked it over real quick and I see it's making a NetBIOS call, which the success of might be dependant on the protocols loaded. Jim Dettman President, Online Computer Services of WNY, Inc.

That DOES change with every format (and every new HD). When was the last time YOU changed your MAC address? As form myself, I've NEVER done so. When was the last YOU formatted (or replaced) your hard disk? As for myself, at LEAST half dozen times over 4 systems just in the last 4 or 5 years. Hmmm.... Never or 1/2 dozen times... John W.

Jees, some BIOS these days even allow you to change your MAC address yourself. -----Original Message----- From: John W.

I learned a long time ago not to sweat the small stuff. If there are hackers figuring out how to hack Microsoft's $100 million copy protection, I am not going to survive a determined attempt to get around my stuff. On the other hand, I assume you lock your front door. And I assume there is glass in the door that anyone who wants in could just smash to reach in and unlock your door. So why do you bother? Because the lock keeps 99% of the people out of your house. 99% is good enough for me. I will not even bat an eyelash nor give a second thought to the other 1%. 99% of the effort COULD be spent stopping (or failing to stop) that last 1%. John W.
