title: How to get the computer name using the IP Address
body: <p>I am trying to get the computer name for the current user.  I am able to get the IP address using <code>System.Net.Dns.GetHostEntry("ComputerName").Address.ToString()</code> but when I replace the *ComputerName*with the <em>IPAddress</em> I receive the following error.</p>
  
  <p><strong>No such host is known</strong></p>
  
  <p>I enabled reverse DNS in IIS7 by running command: 
  <strong>Cscript.exe adsutil.vbs set w3svc/EnableReverseDNS TRUE</strong>
  in the  <strong>C:\inetpub\AdminScripts</strong> directory on my server.</p>
  
  <p>Any ideas on what I'm doing wrong?</p>
  
  <h2>Update</h2>
  
  <p>The overall purpose is that this will be a help desk application and it will be useful for a user to be able to easily provide their computer name for assistance.</p>
  
  <p>Locally everything works but it does not work once published to the server.</p>
