Latest symbols of ntkrnlmp.exe cannot be found from Microsoft public symbol server

Hello,

I received a dump file that is dumped from the system with the latest update.
The dump file reports:

FAILURE_EXCEPTION_CODE:  5E2FC6A7

EXCEPTION_STR:  WRONG_SYMBOLS

IMAGE_NAME:  ntoskrnl.wrong.symbols.exe

MODULE_NAME: nt_wrong_symbols

SYMBOL_NAME:  nt_wrong_symbols!5E2FC6A777D000

Here is my symbol file path

I could not find the symbol of ntkrnlmp.exe with that timestamp from my symbol file path.

Could anyone let me know how to get the symbol file for the dump?

Have you tried
!sym noisy
.reload /f nt

?

Yes.
Here are the messages after setting to noisy.

Sorry if this is an obvious question, but are you sure the machine running windbg actually has a directory called d:\tmp\sym? Remember that path is on the machine with windbg, NOT on the machine being debugged.

The error ERROR_INTERNET_SECURITY_CHANNEL_ERROR can come from an overly aggressive corporate proxy cache. Are you inside a corporate environment with an overly strict IT department?

Yes, it has a directory called d:\tmp\sym on my machine running windbg.

I’ll check my network environment. Thanks for your hint.

@Tim_Roberts Thank you very much. It was my network environment. I have downloaded the symbols.
