虚拟主机ASP.NET网站不幸遇到HTTP 500错误，请问该如何编写用于发布的web.config文件？
服务器环境：
网络服务商提供的虚拟主机，.NET版本为2.0.50727。
运行asp程序没有任何问题，Access数据库的查询与修改都没有问题。
错误：
运行ASP.NET时遇到了无情的HTTP 500错误，与提供商交涉的结果就是他们一口咬定是web.config错误，号称有成功的asp.net 2.0的案例，但他们又不提供可以正常使用的web.config样例。
以下是网络服务商提供的IIS错误信息，麻烦各位高手给分析下，谢谢！

[解决办法]
应该不是web.config的问题，提示如下：
Could not load file or assembly 'Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a ' or one of its dependencies. 系统找不到指定的文件。
你是否正确部署了Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a这个程序集呢
