如何管理IIS，自动创建WEB SITE，应用程序池

有时我们需要动态的创建WEB SITE或都是虚拟目录，比如，当用户申请一个社区后，分配一个二级域名的，一个用户一个Web site。这时我们就可以用到。NET访问IIS的功能，来自动创建了。
需要引用using System.DirectoryServices;这个组件来管理IIS，如果是WEB来访问的话还有权限的问题，一般这样并发的要求性能较高的操作都写成SERVICE后台来处理比较合适。
请看下面的代码片段，
 /// <summary>
        /// 创建应用程序池
        /// </summary>
        /// <param name="AppPoolName"></param>
        public static void CreateAppPool(string AppPoolName)
        {
            bool ExistAppPoolFlag = false;
            DirectoryEntry newpool;
            DirectoryEntry apppools = new DirectoryEntry("IIS://localhost/W3SVC/AppPools");
            foreach (DirectoryEntry a in apppools.Children)
            {
                if (a.Name == AppPoolName)
                {
                    ExistAppPoolFlag = true;
                    break;
                }
            }
            if (ExistAppPoolFlag == false)
            {
                newpool = apppools.Children.Add(AppPoolName, "IIsApplicationPool");
                newpool.CommitChanges();          
            }
        }
        /// <summary>
        /// 给某一个site分配程序池
        /// </summary>
        /// <param name="newvdir">The newvdir.</param>
        /// <param name="AppPoolName">Name of the app pool.</param>
        public static void AssignAppPool(DirectoryEntry newvdir, string AppPoolName)
        {
            newvdir.Properties["AppPoolId"].Value = AppPoolName;
            newvdir.CommitChanges();
        }
//下面这个是修改Web Site的执行脚本。 通常建一个web site default的asp.net 1.1

        public static void UpdateAspdotnetScriptVersion(DirectoryEntry siteVDir,string UpdateScriptPath)
        {
            string fileName = UpdateScriptPath;
            ProcessStartInfo startInfo = new ProcessStartInfo(fileName);
            if (startInfo != null)
            {
                //处理目录路径
                string path = siteVDir.Path.ToUpper();
                int index = path.IndexOf("W3SVC");

问题：我可以正确的创建虚拟目录并指向一台远程的主机，把访问的username & password设置，但它始终是一个web application ，我不想让他成为一个application，只是一个文件夹虚拟目录用来指向远程主机。这个不知道用代码如何现实在
CreateirtualDirectory这个方法里，试过N次不行，有知道的请留言给我。谢谢
