Re: [DUG]: Unique Machine ID....

[Corey Murtagh]

The NIC address of the dial-up adapter is static... AFAIK it's the same on all computers running, at least, the same version of windows.  Or it could be just the same thing across all computers running any variation of Win32 - I haven't checked them all yet <G>   What you need is a way of fingerprinting computers, right?  There are a few problems with this... specifically that identical computers with fresh installs of the same OS (especially if you use ghost to copy an installation) are likely to produce the same fingerprint.  Unless you can get ID codes from the hardware (processor serial, drive serial, etc) then there's not much variation between them.   Short of generating (and storing somewhere) a code of your own (GUID, etc), I can't see a viable way of doing this.  Even then there's not a lot stopping me from using a drive duplicator to install an exact image of my HD to another machine, including whatever you've stored :/   There are usually a few spare bytes at the end of the RTC/CMOS memory, if you're game to try using those :>   -- Corey Murtagh The Electric Monk "Quidquid latine dictum sit, altum viditur."
