Asp.net 无法浏览到WCF服务：HTTP 400错误请求

我有一个调用2个WCF服务的VS2010 MVC3解决方案。在我的第一台电脑上一切正常。我有另一台计算机，在那里我安装了相同的操作系统、相同的VS、相同的SQL Server Express、相同的IIS。。。我在第二台计算机上复制了解决方案的源代码。运行解决方案时，一切正常

但在第二台计算机上：

我无法浏览到服务URL！？一,

我无法更新服务引用！？二,

1当我浏览到http://localhost/PLATONServices/RequestService.svc 我收到一个HTTP400错误请求

2我收到一个HTTP状态为400的请求失败：错误的请求METADATE包含无法解析的引用：'http://localhost/PLATONServices/RequestService.svc"

有什么想法吗

因为两台计算机上的代码源相同，并且第一台计算机上的一切都正常，所以问题出在其他地方。我在两台计算机上都使用IIS6，但我看不出有任何区别

我找了一整天都没找到

谢谢

更新

以下是WCF的跟踪：

确保服务是在应用程序中设置的，如本文所述

WCF相关组件是否安装在第二台机器上？这些是从打开或关闭Windows功能对话框中配置的，该对话框可以在Windows的“添加/删除程序”中找到。它们通常在Microsoft.Net Framework 3.5.1部分下。我安装的与我的另一台计算机完全相同。我还尝试在Microsoft.Net Framework 3.5.1下安装WCF HTTP激活，同时打开或关闭Windows功能，但没有纠正问题。谢谢。你打开/查看服务跟踪日志了吗？这会告诉你什么是故障是的，我已经打开了服务跟踪日志。我更新我的问题以显示痕迹。@Bronza要查看此帖子，我已经查看了此帖子，所有建议都已完成，但未成功。无论如何，谢谢。即使您只是在浏览器窗口中打开服务，也会出现此错误？
