I'm having some issues with a SBS 2003 we have recently taken over support for.
Last Sunday at 00:08 it appears that the server just froze, on arrival at site at 10:30 a.m. the normal desktop screen with the server time showing 00:08 - the mouse is unresponsive and ctrl-alt-del etc does not provide any response etc.
The only way to get this back is to power it down. On power up then it is not possible to login as the server hangs on applying computer settings, left it for over an hour and no change.
In the end started in safe mode and disabled all 3rd party services, except for Blackberry express and it started as normal. Did quite a few restarts after that and it restarted each time o.k.
The plan was to go back in this weekend, and restart each 3rd party service in turn until the culprit was found.
However, this morning again at 00:33 right in the middle of the scheduled backup exactly the same behaviour - screen shows as if the backup was running, can't move mouse and totally unresponsive. Again hard reboot and then hangs applying computer settings, this time had to set all exchange services to manual and reboot in order to be able to logon. After normal restart was able to start the exchange services o.k.
It's almost as if the server just stops at that moment in time. Examing the logs etc - seem to show normal running and then all of the logs, administrative and system etc. - simply stop at that moment in time.
As an aside it looks as though once the server has been logged in to locally the session never actually closes - not sure if this would cause an issue or not.
Not come across this before so am not sure where to start to troubleshoot, especially as the logs appear to provide no information of anything untoward.
