我有一个Windows服务，该服务在网络上的一台计算机上承载WCF服务。我有一个客户端，该客户端尝试连接到网络上另一台计算机上的该服务。当我连接并尝试订阅WCF服务时，收到以下错误：
请求通道在00：00：09.9989999之后等待答复时超时。请增加传递给请求调用的超时值或增加绑定上的SendTimeout值。分配给此操作的时间可能是更长超时的一部分。
我已经在客户端和服务中添加了跟踪功能，试图找出问题所在，但我无法理解它。
下面是服务应用程序配置：

对服务的跟踪显示了来自客户端的连接详细信息，因此它一定在某种程度上通过了。另外，当我从与服务相同的计算机上运行客户端时，一切都运行得很好。我可能需要做些什么才能使远程连接工作？
