并没有端点在网络上侦听.tcp://url可以接受这个消息的.这通常是由不正确的地址或SOAP操作引起的

Question

我有一个使用net.tcp协议的WCF程序。它托管在IIS上，过去工作得很好，但最近(我想在一些windows更新之后(，客户端在尝试连接服务器时报告了以下错误消息：

Error occurs during register duplex connect service. Error msg: There was no endpoint listening at net.tcp://localhost/xxx/Duplex.svc/tcp that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

我可以打开"；http://localhost/xxx/Duplex.svc"在web浏览器中成功。事件日志中没有记录错误，net.tcp协议已添加到我的web应用程序中，net.tcp绑定已添加到默认网站中。net.tcp侦听器适配器服务正在运行。

我能为这个问题做些什么吗？最近是否有任何windows更新会导致此问题？欢迎任何建议。

Answer 1

终于找到了根本原因。默认的NetTcp端口808被"英特尔图形驱动程序"占用。请参阅此链接
我在英特尔论坛上提交了一张罚单，根据他们的回复，这个问题在最新的驱动程序版本中已经解决了。
