看起来你有调试器附加到目标。 （1）忽略WinDbg状态消息。查看是否连接到目标的***方法是尝试一些命令。 （2）当我调试一个虚拟机时，我使用的串行端口也丢失了，但是它看起来像是出来（工作很好）。

It looks like you got the debugger attached to the target. (1) Ignore WinDbg status message. The best way to see if you're connected to the target is to try a few commands. (2) When I debug a virtual machine, the serial port that I'm using also goes missing, but it looks like you figured that out (good job).

为了发出命令，你需要进入内核。单击Debug-> Break，然后尝试以下命令：

In order to issue commands you need to break into the kernel. Click "Debug->Break" and try the following commands:

.reload
!ustr srv!SrvComputerName 

应该给你目标系统的计算机名。

That should give you the target system computer name.

如果您想了解有关内核调试的更多信息，我将在***上查看 TheSourceLens 。对于文学，我不能推荐任何书籍，因为我发现的大多数信息都是在线的。不过，建议您查看 OSR Online 。快乐调试。

If you want to learn more about kernel debugging, I would check out TheSourceLens on ***. As for literature, I can't recommend any books, because most information I find are online. However, I would recommend checking out OSR Online. Happy debugging.
