All,
First, losing the List is really going to hurt me.
My question: Can anyone suggest a way or have a code snippet to
obtain a (relatively) unique identification of a Windows machine? I
have tried wading through msdn stuff but it is way over my head.
I am looking for some information that will remain relatively
consistent and apply to the physical computer. One suggestion was
to look at several environment variables and match at least two of
them to those of the originally licensed machine.
My problem is that I could not find a list of the env variable
names - and have never applied declares - and don't have any idea
of the returned data structure. (Although, I believe I can master
declares after obtaining Charles' book.)
Does the RB system.environment class access Windows machines? Would
this be a good place to start?

These lists will be shut down in a few days
You might look into the Windows Functionality Suite that has a lot of
Windows functions in it already that may help you
That said, be careful about trying to uniquely identify a machine
Many items can be replaced or spoofed
MAC addresses from Ethernet cards can be spoofed, and HD's can be
reformatted so the volume numbers get changed
Combining several items like this may help
I'm not 100% sure what Windows does to decide if IT is running on the
same machine but there is a limit to what you can change before even
it decides you need a new license as it's a "different" machine
