Forum OpenACS Q&A: Re: How to uniquely identify user's PC without using IP address?
David, your script certainly looks like it could work. I need to check if it's a certainty that every PC accessing the site can be named this way.
I also came across this thing that has a completely different way of solving the problem. http://www.mvps.org/vbnet/index.html?code/network/macaddressremote.htm Now I've just got to figure out how to call it!
