此处，RDS01使用 IIS Crypto 手动启用所有（SSL 2.0 除外）后，SCHANNEL 注册表配置单元导出，以明确声明它们已启用

答案1

过去，我曾因以不向后兼容的方式设置客户端通道而感到困扰。您可能应该查看 RDS01 上的客户端协议。

在你的情况下，我会使用 IIS Crypto 来启用全部通过选中所有框并使用“设置客户端协议”设置来（临时）在 RDS01 上设置客户端协议，然后在没有“设置客户端协议”的情况下应用最佳实践。

这应该可以排除任何客户端配置问题。

编辑：

如果这不起作用，我建议使用 Wireshark 来捕获和分析握手，并准确查看 RDS01 呈现的加密套件。我个人会在 APP01 上运行它，这样我就可以轻松地比较好的握手和坏的握手。

答案2

使用 WireShark 进行调试时，我发现了大量 TCP 碎片和重传。调整路由器后卫星发射系统设置，SSL 握手已正确建立。

抱歉，问题不完整，RDS01和服务器位于通过 IPSec VPN 网关RDS02连接到网络的同一网络上。由于正在运行，我没有考虑这种可能性。APP01RDS02

为了解决我的问题，我使用了这个表格并发现 MMS = 1384

  1500   Standard MTU
-   20   IP Header
-   24   GRE Encaps.
-   52   IPSec Encaps.
-  (8)   PPPoE (optional)
-   20   TCP Header
-------
= 1384   MMS

打开路由器管理页面并设置新的 MTU 或 MSS
