The following code returns the string I am trying to return
Public Shared uNT_id = If(HttpContext.Current.User.Identity.IsAuthenticated, HttpContext.Current.User.Identity.Name, System.Environment.UserName)
however if a user logs in and terminates the window, which SHOULD kill the cookie, the HttpContext.Current.User.Identity.Name is still equivalent to the last user to log in. The same holds true if a new user attempts to log in.
