<p>I used code like this to find the remote user name:</p>

<pre><code>banner_label.Text = "Welcome, &lt;B&gt;" + User.Identity.Name + "&lt;/B&gt;!"
</code></pre>

<p>I'd also like to find the remote host name.
My production environment will be a corporate intranet with active directory.</p>

maybe this would work for you
```
```
Request.UserHostName
```
```
edit:
i think what you're trying to do will not working over the internet, what you're trying to get is the name of the computer, which will not be transmitted with the request to the server.
