WCF访问被拒绝

Question

我有一台本地托管WCF服务的PC，我可以在C#程序中添加对该服务的引用。但是，当我运行该程序时，我会收到一个"拒绝访问"错误。除了访问被拒绝之外，我没有得到其他信息。

有人对该怎么做有什么建议吗？我有另一台机器，它看起来设置相同，但能够连接到同一台机器上的本地托管版本。我已经看了其他已经发布的问题，但似乎没有什么是正确的。

发现了问题所在，非常可笑。虽然我认为是IIS或.NET造成的，但我几乎是在讨价还价。问题是Windows防火墙被设置为阻止包括网络流量在内的所有内容。这个问题被张贴在这里是因为我认为它是.NET代码。

感谢Grzegorz、CodeCaster和Shailesh花时间阅读并提供建议。
