The following code sample shows how to update the mapping from the default AccessDenied.aspx application page to a custom application page and display it to the console. The original application page is restored at the end.

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Administration;

namespace MapCustomAppPage
    class Program
        static void Main(string[] args)
            using (SPSite site = new SPSite("http://MyServer"))
                //Get a reference to the web application.
                SPWebApplication webApp = site.WebApplication;

                //Update AccessDenied application page to AxsDnd.aspx.
                webApp.UpdateMappedPage(SPWebApplication.SPCustomPage.AccessDenied, "/_layouts/SubFolder/AxsDnd.aspx");

                //Output the newly assigned application page.

                //Reset the mapping to the default application page.
                webApp.UpdateMappedPage(SPWebApplication.SPCustomPage.AccessDenied, null);

                Console.Out.WriteLine("Press any key...");
