ftp站点的配置问题,高分求救!!!!!!!!!!!!!

我机器是xp系统,iis是5.0版本.我想给默认的ftp站点分配一个用户,用该用户连接ftp站点(代码如下)
private void Download(string filePath, string fileName)
        {
            FtpWebRequest reqFTP;
            string ftpServerIP = "192.1.0.1";
            string ftpUserID = "yutao_lu";
            string ftpPassword = "131421";
            try
            {
                FileStream outputStream = new FileStream(filePath + "\\" + fileName, FileMode.Create);                reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServerIP + "/" + fileName));                reqFTP.Method = WebRequestMethods.Ftp.DownloadFile;                reqFTP.UseBinary = true;                reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);                FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();                Stream ftpStream = response.GetResponseStream();                long cl = response.ContentLength;                int bufferSize = 2048;                int readCount;                byte[] buffer = new byte[bufferSize];                readCount = ftpStream.Read(buffer, 0, bufferSize);                while (readCount > 0)
                {
                    outputStream.Write(buffer, 0, readCount);                    readCount = ftpStream.Read(buffer, 0, bufferSize);
                }                ftpStream.Close();                outputStream.Close();                response.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }
现在的问题就是得到访问ftp站点的用户名:ftpUserID和密码: ftpPassword
请问我要怎么配置ftp默认的站点才能得到呢?
