都是用winfrom写的
问题1：发送邮件程序在xp系统下都能发送，在windows server 2003的系统不能发送

string fjrtxt = "aaa0323@163.com"; //发件者邮箱地址

            string mmtxt = "qq123"; //发件者邮箱密码

            string sjrtxt = "35435345@qq.com";//收件人收箱地址

            string zttxt = "这是厕所";//主题



            string nrtxt = "这是测试";//内容

            string[] fasong = fjrtxt.Split('@');

            string[] fs = fasong[1].Split('.');

            //发送

            SmtpClient client = new SmtpClient("smtp." + fs[0].ToString().Trim() + ".com"); //设置邮件协议

            client.UseDefaultCredentials = false;//这一句得写前面

            client.DeliveryMethod = SmtpDeliveryMethod.Network; //通过网络发送到Smtp服务器

            client.Credentials = new NetworkCredential(fasong[0].ToString(), mmtxt); //通过用户名和密码 认证

            MailMessage mmsg = new MailMessage(new MailAddress(fjrtxt), new MailAddress(sjrtxt)); //发件人和收件人的邮箱地址

            mmsg.Subject = zttxt; //邮件主题

            mmsg.SubjectEncoding = Encoding.UTF8; //主题编码

            mmsg.Body = nrtxt; //邮件正文

            mmsg.BodyEncoding = Encoding.UTF8; //正文编码

            mmsg.IsBodyHtml = true; //设置为HTML格式

            mmsg.Priority = MailPriority.High; //优先级

            try

            {

                client.Send(mmsg);



            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message);

            }

问题2:同样上传图片到服务器，在xp系统下都能上传，在windows server 2003的系统不能上传
客户端代码:

OpenFileDialog openFileDialog1 = new OpenFileDialog();

            openFileDialog1.Filter = "图像文件 (*.BMP;*.JPG;*.GIF;*.PNG)|*.BMP;*.JPG;*.GIF;*.PNG"; //上傳格式



            if (openFileDialog1.ShowDialog() == DialogResult.OK)

            {

                string fullpath = openFileDialog1.FileName;//文件路径 

                System.Net.WebClient myWebClient = new System.Net.WebClient();

                myWebClient.UploadFile("http://localhost/up/Uploader.ashx", "POST", fullpath);  

              



            }

服务器代码：

<%@ WebHandler Language="C#" Class="Uploader" %>



using System;

using System.Web;

using System.IO;

public class Uploader : IHttpHandler {

 

    public void ProcessRequest(HttpContext hc)

    {

        foreach (string fileKey in hc.Request.Files)

        {

            HttpPostedFile file = hc.Request.Files[fileKey];

            file.SaveAs(Path.Combine(hc.Server.MapPath("."), file.FileName));

         

        }

    }

   public bool IsReusable

    {

        get { return true; }

    }   





}
