We have a client with an SBS 2003 server. In the last few weeks it has started hard locking. We get an alert via our RMM tool that it is offline. When we go onsite the numlock key is on, the monitor is sleeping. Pressing any key or moving the mouse does not make the screen resume and the numlock key is stuck on. The hard drives show some occassional activity (I assume this is just the raid card syncing). And the computer cannot be pinged from any other computer. This is an HP Proliant server. We hard power reset it and all is well for about another week. What is weird is there is not many clues in the event log as the entries that are there have been happening for years and there has not been any recent changes to the server.
The last time it crashed was 12-19 @ 8:32PM. That is when the event log says "unexpected shutdown" There are no entries in the event logs until 6:15AM when we reset it.
I am assuming hardware at this point. My plan is to get a new server and do a P2V transfer to it until we can load a new server from scratch and migrate from the old SBS 2003 to the new.
