web配置错误无法在asp.net上的服务器上上传文件

Question

我正在使用下面的web配置上传服务器asp.net 4.0中的文件，但我收到错误重新分级，这是我的web配置代码怎么办？

<?xml version="1.0"?>
<configuration>

  <system.webServer>
     <validation validateIntegratedModeConfiguration="false"/>
  </system.webServer>
  <system.web>
 <authentication mode="Windows"/>

    <add name="myConnectionString" connectionString="Data Source=192.168.1.1;Initial Catalog=temp;User ID=temp;Password=temp" providerName="System.Data.SqlClient"/>


  </connectionStrings>
<system.webServer>

      <add name="AjaxFileUploadHandler" verb="POST" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit"/>
    </handlers>
  </system.webServer>

</configuration>

但我无法在服务器错误上传文件

  Access to the path 'E:\domains\mywebsite.co.in\httpdocs\cover\3128.jpg' is denied.

    FileUpload1.SaveAs(Server.MapPath("/cover/" + Session["upkey"].ToString() + fileName));
