I have a Windows 2008 Server which I use for development work. It hosts both Exchange 2007 and SqlServer 2008.
It runs great...except that roughly once a week it just shuts down. I haven't noticed anything odd in the event logs prior to the shutdown.
Interestingly, for quite a while (months) it used to shut down every Wednesday morning at approximately 7:45 AM. That pattern has since been broken, though.
Is there a way to ramp up the log level for the system so that I can get some diagnostic information about what's causing the shutdowns?
