C# WCF服务器和客户端之间通过LAN的通信失败

我正在尝试在客户端和服务器之间进行通信，这是用C语言中的MicrosoftWCF-netTcpBinding创建的，服务器作为Windows服务运行。服务器作为一台PC在我的虚拟LAN上运行。但通信始终失败，出现错误：

An unhandled exception of type 'System.ServiceModel.Security.SecurityNegotiationException' occurred in mscorlib.dll

Additional information: The server has rejected the client credentials.

在本地主机上，所有操作都正常工作。客户端也从该IP地址下载ServiceReference

我认为问题可能出在配置文件中的安全设置上。请问那里怎么了？因为在服务器系统上的TCPView中，我看到MyService的远程地址只有他的本地计算机名，而不是全部。谢谢你的回复
