Question

什么可能导致错误：

Bad symbols for NTDLL (error 3). Aborting.

使用！cs命令时？

我正在分析键盘强制完整转储并设置了MS符号服务器的符号路径。

lml不会将ntdll列为已加载

.sym嘈杂，重新加载显示：

3: kd> .reload ntdll

"ntdll" was not found in the image list.
Debugger will attempt to load "ntdll" at given base 00000000`00000000.

Please provide the full image name, including the extension (i.e. kernel32.dll)
for more reliable results.Base address and size overrides can be given as
.reload <image.ext>=<base>,<size>.
DBGENG:  ntdll - Partial symbol image load missing image info
DBGHELP: No header for ntdll.  Searching for dbg file
DBGHELP: .\ntdll.dbg - file not found
DBGHELP: ntdll missing debug info.  Searching for pdb anyway
DBGHELP: Can't use symbol server for ntdll.pdb - no header information available
DBGHELP: ntdll.pdb - file not found

DBGHELP: ntdll - no symbols loaded

3: kd> .reload nt

DBGHELP: nt - public symbols  
        c:\symbols\ntkrnlmp.pdb\BF9E190359784C2D8796CF5537B238B42\ntkrnlmp.pdb

是否应该在lm命令中列出ntdll？加载符号或运行这些命令是否需要特殊的东西？

此外，我也很好奇为什么我不能在强制/完整系统转储中转储所有线程：

3: kd> ~* k
   ^ Syntax error in '~* k'

我是否只是无法正确设置windbg，或者这些命令是否适用于其他类型的转储？

Answer 1

之前您似乎已完成用户模式调试。现在您处于内核模式，您可以从x: kd>提示中看到。

内核模式调试与用户模式调试有些不同。最重要的恕我直言：并非所有的应用程序内存（虚拟内存）都可用，只是转储（物理内存）时RAM中的部分。工作集（特定进程的物理内存）。

您可以使用!process 0 0 <exename>

搜索您的可执行文件

0: kd> !process 0 0 NotMyFault.exe
PROCESS ff3b58f0  SessionId: 0  Cid: 05ac    Peb: 7ffde000  ParentCid: 039c
    DirBase: 018c02e0  ObjectTable: e165d728  HandleCount:  35.
    Image: NotMyfault.exe

不幸的是，此时无法进行通配符搜索。然后，您可以使用.process <process>切换到该流程：

0: kd> .process ff3b58f0
Implicit process is now ff3b58f0

要查看主题使用!process <process> 2：

0: kd> !process ff3b58f0 2
PROCESS ff3b58f0  SessionId: 0  Cid: 05ac    Peb: 7ffde000  ParentCid: 039c
    DirBase: 018c02e0  ObjectTable: e165d728  HandleCount:  35.
    Image: NotMyfault.exe

        THREAD ff1d4020  Cid 05ac.05b0  Teb: 7ffdd000 Win32Thread: e1c6e2b0 RUNNING on processor 0

接下来，使用!thread <thread>获取类似于~的输出：

0: kd> !thread ff1d4020
THREAD ff1d4020  Cid 05ac.05b0  Teb: 7ffdd000 Win32Thread: e1c6e2b0 RUNNING on processor 0

如果您在加载符号时遇到问题，请在使用.reload /user后尝试.process <process>。

NTDLL的错误符号（错误3）。中止
