求助：Asp.net 4.0向网络映射驱动器写入文件报错

Question

各位好，目前我的应用服务器如下：服务器A——Aspnet应用服务器，服务器B——文件服务器

我的Aspnet程序试图向文件服务器写入文件时报错“Could not find a part of the path ....”

在提问前，我已在网上搜了大家的解决办法，目前尝试了如下步骤：

1、在A、B中建立相同名称、密码的账户ishareuser

2、在A中建立B共享给ishareuser的文件夹的映射盘Z，使用ishareuser登录

3、在aspnet程序的web.config中加入<identity impersonate="true" userName="ishareuser" password="123456" />

4、将IIS7中的将应用程序池ASP.NET 4.0 Classis的标识设为ishareuser

5、C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files授予了ishareuser写入权限

执行程序，仍然报错，不能找到路径的一部分

另外，我的操作系统是win7，我很疑惑，我跟大家用的方法一致，为什么到我这就不行了呢，哪位高人给解答一下啊，谢谢了

我很奇怪的是我在配置文件里明明加上了模拟的配置节，但事件查看器里的却说“ Is impersonating: False ”

而且，我把两台服务器里的用户都加到了administrators组里
