If I had hair, I would pull it out! This one is driving me crazy! I have a new Dell 420 server running Windows SBS 2011. The system was migrated into an existing 2003 enviroment and is running all 5 roles, hosts Exchange and Sharepoint. There is another 2003 server acting as a communications server and backup DC.
My problem is the server shuts down on it's own about once a week with NO notice, NO event log entries, it just shuts down??? The Dell OSM shows "an OS shutdown" in the logs so I assume that it's Windows doing it. There is NO scheduled events to shut it down. We have removed AVG, disabled BUEXEC 2010 and any non-essential services with NO luck.
The logs are reasonably clean, nothing specific.
The only role that the server is not performing is DHCP due to firewall issues.
Any help before I have to call my favorite software vendor (Microsoft) would be appreciated.
