Get UserName in Web App
<p>I have an ASP.net app which is being hosted on a server. I want to get the Clients username from the system and use that name as a title for an XML file im saving on the server. 
I have tried various different mathods such as:
Environment.UserName();
WindowsIdentity.GetCurrent();</p>

<p>However all that keeps returning is the NetworkService account  name on the server.</p>

<p>Can anyone assist with this.</p>

<p>thank you</p>
