.reload命令後連接丟失到目標

Question

在WinDbg中：文件 - >符號文件路徑？設置我試圖使這個例子 Srv*c:\symbols*https://msdl.microsoft.com/download/symbols 這個路徑文件後： https://msdn.microsoft.com/en-us/library/windows/hardware/mt269367 在第5節第2步，當我鍵入.reload /f失去了調試器連接到 目標我設置的路徑。 如果我沒有設置符號文件路徑，WinDbg也會在同一點進行破解。

對我來說，似乎windbg失去了與目標的連接，並沒有得到它 重新建立。即使我在VM上重啓目標系統。

有人可以告訴我發生了什麼事，我做錯了什麼或爲什麼會發生這種情況？

我正在使用VMWare Player。我的主機和目標操作系統是Windows 10 Pro。 VMWare被配置爲在NAT中使用網絡。 Echo驅動程序已成功安裝。

問題解決。 將虛擬機設置從以太網更改爲COM。 我還通過使用this網站進行設置，將bcdedit調試設置更改爲COM端口。 現在我可以調試並重新載入符號或驅動程序。
