ASP.Net Webservice 500-内部服务器错误

我已经创建了一个Web服务，我在本地机器的IIS7中托管了它，它可以毫无问题地工作，并且可以在LAN中使用。 然后，我将它托管在一个付费的Microsoft Web服务器上，但一旦我打开.asmx或浏览器上的任何其他页面，它就会给出以下错误消息

500-内部服务器错误。 您正在查找的资源有问题，无法显示

我的web.config显示在下面

5xx错误是内部错误，通常与您的代码或服务器中缺少的某些配置有关，因为它是付费主机，我想这是您的代码有问题，请尝试启用详细错误页面。将此添加到web.config

  <system.web>
    <customErrors mode="Off">
   </system.web>

---

请记住在调试完成后将此选项更改回原来的位置。好的，我们必须查看是什么地方出了问题或是什么原因导致了错误。因此，要开始添加这一行

<customErrors mode="Off"/>

在

<authentication mode="Windows"/>

在web.config文件中

然后尝试加载您的页面，它将生成一条详细的错误消息，以及错误发生的确切位置，即检查代码ajax部分的url（Web服务地址）
