Understanding the reasons why a server was rebooted can involve checking various logs and system records. Here are the key steps to identify the cause of a server reboot: 1.
Check the Event Viewer (Windows Servers): - Open the Event Viewer (
eventvwr.msc
). - Navigate to
Windows Logs > System. - Look for
Event ID 1074 (The system has been shut down by a process/user) and
Event ID 6008 (The previous system shutdown was unexpected). 2.
Examine Shutdown Logs: - Review the shutdown logs to see if there is any record of software or user-initiated reboots. 3.
Analyze System Crash Dumps: - If the system experienced a crash, there might be dump files located in the
C:\Windows\Minidump directory. Use tools like
WinDbg to analyze these dump files. 4.
Review Scheduled Tasks and Maintenance: - Check if there were any scheduled tasks or maintenance windows triggering the reboot. 5.
Analyze User Actions: - Investigate if any administrators or users initiated the reboot manually or via scripts. Here is a BBCode table to help you find and analyze these logs and actions:
Step | Description |
---|
Event Viewer | Check for Event IDs 1074 and 6008 in Windows Logs > System. |
Shutdown Logs | Review shutdown logs for records regarding reboots. |
System Crash Dumps | Analyze files in C:\Windows\Minidump using WinDbg. |
Scheduled Tasks | Inspect any tasks or maintenance windows that might have initiated a reboot. |
User Actions | Verify if administrators or users caused the reboot manually or via scripts. |
