System.Security.Principal.WindowsPrincipal p = System.Threading.Thread.CurrentPrincipal as System.Security.Principal.WindowsPrincipal; is null
HttpContext.Current.User.Identity.Name; is null

How can ı solve this

Answer 1

Just disable anonymous authentication and enable windows authentication. Windows authentication may not be installed. If so, it will not work in any way. Go to server roles on Windows Server or windows features on Windows 7 / 8: complete manual .
