Every morning my exchange server reboots. Unfortunately we only have one. I intially thought it might have been my backup job since the reboots occurred at that time. But it definitely is not related to that because over the weekend several backup jobs completed successfully without rebooting exchange.
Last week we service packed Windows 2003 to SP2 and Exchange 2003 SP3 to SP2 of exchange. I have been having this random reboot issue every since. It seems like when the online defrag kicks off around that time the store.exe service hoses up and causes a reboot of the server. Again this is my only Exchange server and currently I am trying to map out a plan to get to exchange 2007.
I cant afford for this server to reboot and not come back up. It could very well be hardware related but I am not 100% sure as nothing indicates in the any logs... If someone can give me direction I would appreciate it.
