.reload 命令后与目标的连接丢失

Question

在 WinDbg 中：文件 -> 符号文件路径？我将路径设置为： Srv*c:\symbols*https://msdl.microsoft.com/download/symbols 在此路径文件设置之后，我正在尝试制作此示例： https://msdn.microsoft.com/en-us/library/windows/hardware/mt269367 在第 5 步的第 2 步中，当我键入 .reload /f 时，调试器失去了与目标。如果我不设置符号文件路径，WinDbg 也会在同一点中断。

对我来说，似乎 windbg 失去了与目标的连接并且没有得到它再次成立。即使我在 VM 上重新启动目标系统。

谁能告诉我这是怎么回事，我做错了什么或者为什么会这样？？

我正在使用 VMWare Player。我的主机和 Target OS 是 Windows 10 Pro。 VMWare 配置为使用 NAT 中的网络。 Echo驱动安装成功

在下面你可以看到WinDbg日志：

问题已解决。将 VM 设置从以太网更改为 COM。我还通过使用 this 网站设置将 bcdedit 调试设置更改为 COM 端口。现在我可以调试并重新加载符号或驱动程序了。
