我有一个WCF服务,它在机器B上运行,并在机器A上有一个客户端 . 这个远程连接工作得很好 . 我没有app.config文件,因为所有连接都是通过代码完成的 . 我正在使用Tcp .

当我尝试在SAME计算机上运行服务器和客户端时出现问题 . 我得到异常: The Server has rejected the client credentials. 内部异常: The logon attempt failed 当我将客户端和服务器放在同一台计算机上时,为什么会失败?

完整的服务跟踪在这里:

    尝试使用机器B的内部IP(192.168 ...)访问服务 .

    如果您仍然遇到问题,则可能意味着它与您的IIS服务器身份验证配置相关,这意味着只有计算机A才有权连接到您的服务器(即Windows身份验证或特定用户) .

    如果它与内部IP一起使用,那么机器B上的某些内容就阻止了来自localhost(127.0.0.1)的请求 . 您可能需要检查高级防火墙设置,或再次检查IIS服务器配置 .
