One of our customers has an HP Proliant ML350 G5 running SBS 2003 R2. Two or three times a day it will reboot or shut down. It does so in an orderly manner (ie it does not crash), and it gives an event of USER32 ID 1074 "The process explorer.exe has initiated the restart (or shutdown) of SERVER1....." The reasons it gives are various ie Reconfiguration (Planned) or Application Installation (Planned), They are always logged as "Planned". It has just run over the weekend with no problems. HP have asked me to install the latest BIOS and PSP which I will do today. I have even considered the possibility of hacking but I don't think that is the case. It may be useful to know that previously the system has been inclined to randomly restart unexpectedly (ie NOT in an orderly manner), it is these last few days where the symptoms seem to have changed to orderly reboots. Any ideas would be appreciated.
