How can I get the client machine username in ASP.net?

In the Localhost, my username is "MTA" when this code is called:

string opl = HttpContext.Current.User.Identity.Name.ToString();
TextBox1.Text = opl.Substring(opl.IndexOf(@"\") + 1);

OR this code:

string opl = System.Environment.UserName.ToString();
TextBox1.Text = opl.Substring(opl.IndexOf(@"\") + 1);

But after publishing and accessing a website with Windows Server. My username is now "SRVCMAN".

    // will return the computer name

    string s = Request.ServerVariables["SERVER_NAME"] ;

   //will return Windows account for the user.

    string s = Request.ServerVariables["AUTH_USER"] ;

I think you are trying to get this information:
