无法浏览到WCF服务：HTTP 400错误请求

Question

我有一个VS2010 MVC3解决方案调用2个WCF服务。在我的第一台电脑上一切正常。我有另一台计算机，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我的解决方案的源代码。运行解决方案时一切正常。

但是这第二台计算机上：

• 我无法浏览到服务URL！？ （1）

• 我不能做“更新服务参考”！ （2）

（1）当我浏览到HTTP：//localhost/PLATONServices/RequestService.svc我有一个HTTP400 BAD REQUEST错误。

（2）我得到了一个请求失败的HTTP状态400：不良请求元数据包含无法解决的参考：'http：//localhost/PLATONServices/RequestService.svc'。

有什么想法？

由于两台计算机上的代码源都相同，并且第一台计算机上的所有内容都正常，因此问题出在别的地方。我在两台计算机上都使用IIS6，但看不到任何差异。

我整天搜索没有成功。

谢谢。
