using System; using com.vrm.com; namespace StarTrack { public partial class administrativeMasterPage : System.Web.UI. MasterPage { private string welcomeMessage = Welcome  ; protected void Page_Load( object sender EventArgs e) { ////authenticate user if ( ADAuthentication .isAuthenticated()) { lblWelcomeMsg.Text = welcomeMessage + SessionHandler .UserName; lblWelcomeMsg.CssClass = aspLabel02 ; } else { //Redirect to Error Page Context.Items[ Message ] = generalconstant .ERR_NOTAUTHENTICATED; Server.Transfer( error.aspx ); } } } } When I debug it it states: System.NullReferenceException: Object reference not set to an instance of an object.
