我有一个不可能的时间让asp.net 4.0以任何方式工作。事实上，我完全擦掉了我的服务器，并重新安装了Server 2008 R2 Standard（运行在VMWare ESXi盒子上，并非它应该重要），甚至无法让测试.aspx页面正常工作。Windows Server 2008 R2 + IIS 7.5 + ASP.NET 4.0 = HTTP错误500.0
这里正是我所做的：
- 安装2008 R2标准
- 激活的Windows，并启用了远程桌面
- 安装必要的角色服务的Web服务器角色（普通HTTP，asp.net ，日志记录，跟踪，管理服务和FTP）
- 启用管理服务
- 通过网络可执行文件安装.Net Framework 4.0
- 新增FTP发布到默认的Web站点
- 交换默认网站应用程序池ASP.NET 4.0（集成）
- 增加了一个 'Test.aspx的' 文件到Inetpub \ wwwroot文件夹（以下内容）
- 打开浏览器到http://localhost/test.aspx并收到500.0错误（也在下面）
我在想什么？我有一段时间（3年以上）没有碰过IIS，所以它可能是愚蠢的/平凡的。请指出，请给我打电话;我的自我可以接受。
谢谢， 戴夫
Test.aspx的

我在使用.NET 4.0 IIS7.5 WIN2008 R2 x64的完全相同的问题。 任何人都找到了解决方案...我已经尝试了所有我能想到的！ – 2010-08-12 13:31:58
重新启动服务器似乎已经修复它...似乎修复大多数Windows问题！ – 2010-08-12 13:47:28
