Unable to load image ntoskrnl.exe的问题

最近在分析一个蓝屏dump时发现，nt模块加载不了符号表，其他系统驱动的符号表都能加载成功

3: kd> .reload /f nt
Unable to load image ntoskrnl.exe, Win32 error 0n2
*** WARNING: Unable to verify timestamp for ntoskrnl.exe
*** ERROR: Module load completed but symbols could not be loaded for ntoskrnl.exe

激活详细符号加载信息

3: kd> !sym noisy

但是提取对方电脑上的ntoskrnl.exe用IDA分析，发现可以正确加载到符号表，于是我将提取到的ntoskrnl.exe放到windbg要找到的路径上去例如：

SYMSRV:  d:\mysymbol\ntoskrnl.exe\56BCC7865ec000\ntoskrnl.exe not found

结果这次终于正常加载上了

3: kd> .reload /f nt
DBGHELP: d:\mysymbol\ntoskrnl.exe\56BCC7865ec000\ntoskrnl.exe - OK
DBGENG:  d:\mysymbol\ntoskrnl.exe\56BCC7865ec000\ntoskrnl.exe - Mapped image memory
