我有两个 WCF 服务托管在 Windows Server 2003 计算机上的单个 Windows 服务中。如果 Windows 服务需要访问任一 WCF 服务（例如发生定时事件时），它将使用公开的五个命名管道端点之一（不同的服务协定）。该服务还为这两个服务公开 HTTP MetadataExchange 端点，并为服务器外部的使用者公开 net.tcp 端点。
通常情况下一切都很好，但每隔一段时间我就会收到一条错误消息，如下所示：
System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at net.pipe://localhost/IPDailyProcessing that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. ---> System.IO.PipeException: The pipe endpoint 'net.pipe://localhost/IPDailyProcessing' could not be found on your local machine.
--- End of inner exception stack trace ---

它不会可靠地发生，这令人发狂，因为我无法在想要的时候重复它。在我的 Windows 服务中，我还有一些定时事件和一些文件侦听器，但这些事件相当罕见。有谁知道我可能遇到问题的原因吗？任何帮助将不胜感激。
检查“Net.Pipe Listener Adapter”服务是否正在服务管理控制台中运行。 WAS 使用它来接收命名管道上的任何请求。
