How do I get the name of the computer accessing my web page in VB?

I've already tried these methods:

• System.Net.Dns.GetHostName
• Environment.MachineName
• My.Computer.Name
• Environ$("computername")

Each returns APPDEV, which I assume is the name of the server hosting my web page.
I've even asked friends to try my page with these methods and they see the same thing.
How can I get it to return the PC name entered at initial setup, like Joseph-PC?

Since the browser won't tell the computer name to the server, a web page is (thankfully) not able to know your computer's name.
