Can I get Mac address in ASP

[bamodeo]

I am creating a survey application and want to make sure that only one entry per computer is allowed. I don't want to mess with cookies because some people disable them. I also don't want to use the IP address (I already know how to retrieve that) because my understanding is that if people are accessing the web through a proxy server, then two different computers submitting a survey through the same proxy server will show the same IP address in my application.

So, that leaves the Mac address. However I can't seem to find anything that returns that value in ASP. Does anybody know how to do it? Or, if there is a better way to accomplish this, I would appreciate any suggestions.

Thanks,

Brad

i don't think the MAC is accessible by ASP.

tracking their IP address is another option

we have the same problem with our control panel, what we did was to add a script to the page that prompt user when they disabled cookie
