Can't get windows id of user

I'm have an application that i recently switched to run on a service account.  The application pool runs under the service account and executes all the stored procedures.  Before i made this change i was able to grab the windows id of the logged in user and pass it into a stored procedure variable.  Now, though


is returning a null value.
protected void GetObjects_Specific(Object sender, EventArgs e)
        //Remove the session state variable if it exists
        txt_PWReason.Text = "";
        // set the session state variable
        Session["int_ObjectID"] = ddl_AllObjects.Text.ToString();

        DataView dvw_SpecificObject = (DataView)usp_SpecificObject_SELECT.Select(DataSourceSelectArguments.Empty);
        foreach (DataRowView dvw_DataRowView in dvw_SpecificObject)
            string str_ddlAllObjects = Session["int_ObjectID"].ToString();
            lbl_ShortDescr.Text = dvw_DataRowView["vch_ObjectDetail"].ToString();

        if (string.IsNullOrEmpty(System.Web.HttpContext.Current.User.Identity.Name.ToString()))
            txt_CurrentUser.Text = "it's null, get over it";
            txt_CurrentUser.Text = System.Web.HttpContext.Current.User.Identity.Name.ToString();

Open in new window

Some progress.  

  txt_CurrentUser.Text = WindowsIdentity.GetCurrent().Name;

will at least return my service account.  

So now I need to figure out how to get the true login id of the computer and not the account running the application

It's running as a service so the user is the service account (which apparently comes back null). Multiple people can be logged on at the same time, so who's to say which user to use? I suppose you want the ID of the active user. This really isn't usually done since services aren't supposed to be 'snooping' on users. The standard way to do it would be to have it communicate with a user application that the user starts or that automatically starts.

Of course, if no user is active (or logged in) the service will still run and a null would just be expected (and correct).

Are you using Windows Authication?
IIS7+ - Under IIS -> [Application] -> Authentication
IIS6  - Under IIS -> Virtual Directory -> right-click -> Manage -> Directory Security tab
      Under Anonymous access and auth. -> click Edit

Make sure that Integrated Windows Auth is enabled or checked.

Thanks Tommy.  I am going to have to create a login page for the application.
