In the past 24 hours our Windows SBS 2003 server has twice experienced an unexpected shutdown, resulting in the server going into a power off/standby state - not an OS standby.
Upon restart (finger on the power button type), the usual "why did your server unexpectedly shutdown" messages occur; however, the event logs shows no indication of what might have caused this. The events simply stop and restart at the point at which the power is back on. There are no indications of Blue Screening, nothing. The server is in a locked room with limited RDP access.
I realise that I have only supplied limited info but has anyone ever experienced anything like this?
