Hello,
Running SBS 2011 Essentials SP1. The system was installed in January 2012 and was running without any problems. Since clock change at October 28th the system stops four times with an unexpected shutdown. Any relationship with the clock change??
Of course the shutdowns happens not within normal working hours.
Two times there was also a BSOD, after switching on the monitor. But this happens hours after the shutdown. I have no explanation for this behaviour and I can't find any reason for the shutdowns within the errorlogs.
Recent Windows-Updates were installed at October 24th from WSUS, not finding any patch in error
Scanning the complete machine with Symantec EP 12.1 was successful.
Also the hardware/memory test runs without problems.
All VPN connections are disabled for testing with no improvement.
All scheduled taks running without any errors. Furthermore there is no time scheme visible.
No more ideas where I can find the cause for the shutdowns.
Thanks in advance.
Helmar
