WCF "对SSPI的调用失败，见内部异常"

问题描述 投票：3回答：2

我们现有一个使用WCF的系统，一直工作得很好，直到昨天，突然在我的机器和另一台开发机器上都停止工作了。

我已经在客户端配置中设置了系统诊断，写了一个跟踪文件，我们看到了以下异常。

如果我们将安全模式设置为 "无"，在... 两者 客户端和服务器，然后它的工作。

这里会有什么问题呢？

原来造成这个问题的是当天发生的一个windows更新（奇怪的巧合）。更新的内容是 kb3102467 (也就是.NET Framework 4.6.1)--它最终会在机器上找到自己。

事实证明，我们正在使用的SSL证书使用RSASHA512，根据我所读到的内容，它导致了高CPU使用率，因此被禁用（有一个针对这个问题的热修复程序，我看到注册表信息被添加，但在kb3102467之后，它仍然发生）。

作为一个变通方法（在我们发布新的SSL证书之前），我已经用以下方式禁用了TLS 1.2。

  1. 启动regedit并浏览到以下位置: HKLM/System/CurrentControlSet/Control/SecurityProviders/SChannel/Protocols。
  2. 在协议下创建以下密钥。TLS 1.2
  3. 在TLS 1.2下创建以下两个密钥：客户端和服务器。
  4. 在客户端和服务器密钥下创建以下DWORD。DisabledByDefault和Enabled
  5. 在客户端和服务器下设置以下内容。DisabledByDefault=1，Enabled=0。
  6. 重新启动服务器。

这样就解决了问题，不需要卸载掉 kb3102467

我在windows 10上的localhost上测试时得到了一个错误，并认为与大家分享。

在客户端的App.Config中，我删除了下面一行注释。

  <!--<identity>
                <userPrincipalName value="AD\7329688" />
            </identity>-->

现在它的工作
