Good morning, my WS 2019 physical server is a Hyper-V Cluster node, has presented a memory dump but the DUMP is not found in the location.
In logs I see the following BugCheck:
The computer has rebooted from a bugcheck. The bugcheck was: 0xc000021a (0xffffe38ec05baa30, 0xffffffffc0000006, 0x00007ffc6c8ea252, 0x0000009a8c39dc00. A dump was saved in: C:\Windows\Minidump\032422-17015-01.dmp. Report Id: 2e327f5f-3528-43dc-87cd-bca7b0ebeeb0
I don't see errors related to WinLogon,
the Microsoft link, I can't find a possible specific cause. ( https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-0xc000021a--winlogin-fatal-error )
Recently I have not installed any application, but 6 days ago I applied the Updates for the month of March-2022.
It is possible to determine something.
I appreciate your opinions and help.
