This is becoming a nightmare, we have no clue on why this server is rebooting each 800 minutes.
This issue started on the night from 05th to 06th of January, so it is a kind of present.
I come form the linux world, so I'm a bit lost, let's see if I can explain the situation properly.
First of all, the uptime of this computer: Easy to see a patern.
Then the event viewer, it's in spanish but and Image is 1K words:
Application events: (only info stuff)
And system events:(only info stuff)
We have done a checkdisk , and everything is fine.
Scheduled tasks have nothing weird, in fact there are only the original ones, no scheduled task from ourselves.
No new programs have been installed.
Hardware looks fine.
Windows is licensed.
A friend checked the minidumps and he found nothing.
What else can we check? Is there any automated check to check everything?
Responding the questions:
Filtering on event 1074 :
It reboots each day , since 6th of January.
On the 9th I see a planed reboot for update. The eventdata states : C:\a68ceedd0c82c60dade2e4b830b8f9\spinstall.exe
Second time on 9th : unplaned from explorer.exe Third time on 9th: reboot without titles from winlogon.exe
And so on, all the reboots seen here are planed on the way to try to fix this issue, none of them worked. Would you like to see the details from them? (just ask)
Number of minutes on the reboot: 849 minutes each time.
Remember that we installed some patches and rebooted, so there are a few that do not last for 800 minutes.
