var MachineName = HttpContext.Server.MachineName;
var BrowserName = HttpContext.Request.Browser;
var Ip Address = HttpContext.UserHostAddress;

You can get information with these codes.

You can try to fetch user's name with the following piece of code: 

var userName = HttpContext.User.Identity.Name;

User.Identity is automatically populated if you use any authentication (example: cookie based, etc)

try this.

 var user = System.Security.Principal.WindowsIdentity.GetCurrent().Name;

it returns Domail/User

Do not forget to put this in web.Config

<identity impersonate="true"/>

Go to the Web.Config file for your application (be sure it's the main one, not the Web.Config under Views), remark out <authentication mode="Forms"> if you see it, then add lines like this:

<authentication mode="Windows"/>
<identity impersonate="true"/>
<authorization>
  <allow roles="DOMAIN\PersonnelGroup" />
  <allow users="DOMAIN\jdoe"/>
  <deny users="*"/>
</authorization>

You don't have to include the <authorization> section but it's useful if you want to allow access for certain groups and users, and deny everyone else. When you use IE, the credentials get passed along automatically. You can test this by printing the username in your view:

@HttpContext.Current.User.Identity.Name

If you open your site using Firefox or any other browser besides IE, it will prompt you for the username and password because it's not automatically passing along the credentials (although apparently you can get Firefox to pass along the credentials, as Dan Diplo mentions above).

If you want to pass these credentials along to another server, such as a SQLServer, it becomes more of a headache from my experience, because you run into a double hop issue. The only workaround I know of is to host IIS and SqlServer on the same server, or have a login for your intranet so you have the username and password to pass along to SQLServer.

You can use HttpContext.Current.User.Identity.Name if you set up the site to use Windows Authentication. Many browsers will pass the username on transparently.

What version of Windows is this mvc app running on?

You could try the following:

  • Use IIS Manager to disable anonymous access to the site, and make sure digest and/or windows authentication is enabled.
  • Change the mvc app's web.config to use Windows Authentication
  • Access the login name in the controller using User.Identity.Name.

Would that do?

If you set IIS to use Windows Authentication and the site is in the Intranet Zone for your clients then the logins will automatically happen without any prompts at all.
