How can I get client machine user login in ASP.net?

On Localhost my username is 'MTA' when calling this code:

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

OR this code:

string opl = System.Environment.Us开发者_如何学CerName.ToString();
TextBox1.Text = opl.Substring(opl.IndexOf(@"\") + 1);

But after publishing and accessing the website from a Windows Server. My username is now 'SRVCMAN'.

For this to work go into IIS click on Authentication and disable Anonymous Authentication and enable Windows Authentication

And then use this code:

var ident = (System.Security.Principal.WindowsIdentity)HttpContext.Current.User.Identity;
If(!ident.IsAnonymous && ident.IsAuthenticated)
{
  var loginUsername = ident.Name;
}

    // will return the host name making the request

    string s = Request.ServerVariables["REMOTE_HOST"] ;
-----------------------------------------------------------------
    // 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 try to get information like this:

IIS Server Variables

I believe you are looking for implementing Windows Authentication Mode.
