我是 AWC/EC2 环境的新手，并在我的 Windows Server 和 IIS 的 EC2 实例上创建了一个 .Net WCF 服务。

导航到http://www.websiteservice.com/MyWebsiteFeederService.svc?wsdl会调出 WSDL。

现在，在同样位于同一台机器上的 www.mywebsite.com 中，我已经使用了 Web 服务。不幸的是，每当我尝试通过该站点访问该服务时，我都会继续收到“访问被拒绝”错误消息：

异常详细信息：System.ServiceModel.Security.SecurityAccessDeniedException：访问被拒绝。

我不认为这与AWS-S3 错误有关 - Access is Denied错误，因为我没有使用存储桶。

在站点的 Web.config 中，我打开了跟踪侦听器并查看了服务跟踪查看器。

这些信息似乎没有用，因为这是我得到的：

[TraceRecord] 严重警告 TraceIdentifier http://msdn.microsoft.com/en-US/library/System.ServiceModel.Diagnostics.ThrowingException.aspx 描述抛出异常。应用域 /LM/W3SVC/4/ROOT-2-129966419874659765

我在另一台非亚马逊服务器上运行完全相同的服务，并且运行良好。我不记得设置任何特殊权限或“以 [用户] 身份运行” - 在 IIS 管理器权限中没有设置其他用户。

我还使用 sqlcmd 从该服务器上的命令提示符确认我可以连接到 RDS 数据库服务器。

在这一点上，我基本上是在绕圈子，希望能得到一些帮助。

谢谢。

错误本身“访问被拒绝”。不是很有帮助。调试信息也不是。

最终，在这种情况下，问题在于需要将执行权限授予正在执行从 WCF 服务调用的存储过程的用户 ID。
