John, as an alternative you could use the serial number of the harddisk
format.
When a disk is formatted it receives a serialnumber that can be used for
this purpose.
If the disk is reformatted than you would get a new serial.
This looks more appropriate to me then a mac address. I used a while ago
in a app that needed protection.
When is disk is re-formatted your software needs to be re-installed
anyway.
When using togheter with some easy challenge/response code you can
re-activate the user by phone.
I don't have the code overhere but if you need it please met me know?

That may have done it, at least for my computer. This appears to be one
of those things that may be windows version dependent.
Thanks anyway, it does seem to work for mine!

Yea, but you have to start somewhere. More and more NICs are embedded
right in the motherboards so this is getting less and less likely.
