I'm sorry. The "database" was referring to my last post. I meant can I build some redundancy checks into the INI file I was starting with. I wrapped database in quotes because I know that an INI file surely isn't a database.

So, rather than trying to do multiple checks on the info you are suggesting to go with CPU ID. I remember something with being able to turn off the CPU ID in the bios. That could cause some issues, correct?
