I have a workstation that is rebooting randomly and frequently. I was able to pull the DMP file and run it through the Debug Diagnostic Tool. The report is short, but does identify the process image as "ntkrnlmp.exe".
The tool also reports that "DebugDiag failed to locate the PEB (Process Environment Block) in MEMORY.DMP, and as a result, debug analysis for this dump may be incomplete or inaccurate." The incomplete part certainly seems to be true.
Your expert advice as to further steps to troubleshoot this issue are greatly appreciated.
