Get the logged username to ASP.net application

Question

I have this application I need to get the name of the windows logged user. I hosted this on a server. When I am tested locally this works perfectly but when I hosted on the server the program returns the server name, not the logged user username. My code is mentioned below

Index.cshtml

<h1>Hello @ViewBag.UserName</h1>

Controller

public ActionResult Index()
{
    string name = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
    string x = "";
    x = name.Split('\\')[1];
    ViewBag.UserName = x;
    return View();
}

Web.config

<system.web>
    <compilation debug="true" targetFramework="4.8" />
    <httpRuntime targetFramework="4.8" />
      <authentication mode="Windows"/>
  </system.web>

Any help is appreciated. Thank you.

Since you're using MVC in.Net framework, you can get the user's name/identity using:

string name = User.Identity.Name;

The reason it's returning the server is that WindowsIdentity.GetCurrent() returns the identity under which the thread is running, while User.Identity returns the identity which was passed to IIS.
