System.Security.Principal.WindowsIdentity.GetCurrent().Name is Works

Hi i am using "System.Security.Principal.WindowsIdentity.GetCurrent().Name " to get the client machine username,with windows authentication in my web.config. My question is that whether this code works when i put the page in intranet.Did i able to get the user name who ever logged in my page by using this...b'coz i need to create a session of the username and proceeds further.

This the Code I am using

void Authenticate() { string strLogin = null;

    try
    {
        strLogin = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
        Session.Add("Login", strLogin);
        //Label1.Text = strLogin;
        //Label2.Text = System.Environment.UserName;


    }
    catch (Exception ex)
    {
        Response.Write(strLogin);
        Response.Write("<br/>handled:" + ex.Message.ToString());
        Response.End();
    }
    finally
    {
        GC.Collect();
    }
}

From stackoverflow

• If your users logon on your website, the you can get the name of the current user with Page.User.Identity.Name.

• Yes. and it also works in Page.User.Identity.Name

• You will need to configure the application to impersonate the Windows user who is accessing it by adding the following element after the authentication element in the Web.Config:

  <identity impersonate="true"/>
  

  If you do not set impersonate to true then the worker process runs as the Network Service or ASPNET account, depending on your version of IIS.

  Xyz : thanks for the replies.How could i test this windows authentication in local machine as i dont have intranet,and systems under domain.
