Question

我有一个VS2010 MVC3解决方案，可以调用2个WCF服务。我的第一台电脑上的一切正常。我有另一台计算机，我安装相同的操作系统，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。

但是在第二台电脑上：

我无法浏览服务网址！（1）
我不能做“更新服务参考”！（2）

（1）当我浏览 http：//localhost/PLATONServices/RequestService.svc 时，我收到了HTTP400 BAD REQUEST错误。

（2）我收到了一个请求失败的HTTP状态400：坏请求元数据包含无法解析的参考：'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，但我看不出任何差异。

我整天搜索都没有成功。

感谢。
