When it comes to troubleshooting spontaneous reboots on Server Core we need to make sure that we have some sort of memory dump file.
In some cases we saw dump files such as when we were initially dealing with the CLOCK WATCHDOG TIMEOUT (blog post) issue. But that has not been consistent.
So, to set the Server Core installation to create a MiniDump file we do the following:
- wmic RECOVEROS set DebugInfoType = 3

We use the Crash Analyzer for MSDaRT Tool included in the Microsoft Desktop Optimization Pack to work with the dump files.
