I know I could use MAC address, but then I have to go to the trouble to enumerate all the MAC addresses and allow the user to decide which to use and store that. Is there another ID one can pull off a given PC that is accurate 99%+ of the time? If 1% of the time they have to call, that is OK. I am going to write a web service that handles the activation and key to PC management.

In our VFP applications we get a value based on the serial number of the hard drive and it has worked for 10 years in some applications, they just have to call when they get a new drive or PC.

Any thoughts on a "better" way in .NET short of MAC?

I am also looking for activation/protection alternatives look at this post http://forum.strataframe.net/FindPost21518.aspx

In my VFP applications I use a commercial library which allow me to activate the licenses online, but it is not easy to implement and maintain, also now with .NET having the need to be installed in each workstation I am having problem trying to implement this solution.

I guess the guys at MicroFour should get the activation module project a top priority
