Called into an environment where a SBS failed and a temp server was put inline as a spare which started failing losing power, shuts off with no log file or any type of report generated whatsoever. This server was replaced with a SBS2011 however another server that holds data is shutting down now same as the temp server did (no warning or log file). I'm reluctant to move the data to the new SBS thinking maybe there is a virus in it. I do have Trend Micro running on the new server. Seems strange the old sbs had motherboard / power issues, the replacement / temp server shut down without any indication and now another server is powering down without any indication as to why. Spoke with Dell and they said it could be an installation issue, virus, or there was third party free anti virus they said could cause something like this (3rd party free av virus software has been removed).
Something else to consider the new SBS2011 is on the same circuit as the server shutting down and it's running fine. The failing server was also moved to another room and still shuts down. Also, the building is notorious for having power glitches especially when the AC kicks on. My thoughts are maybe the older equipment power supplies finally had enough spike and are now out of tolerance however I did run Dell Open Manage and it didn't report anything.
All devices are behind a UPS as well.
Thoughts about moving data on the failed server to the new SBS, there's no indication there's a virus and I did scan with av software (unless ee thinks the loss of power is a virus).
All servers are Dell PowerEdge, the new one has dual power supplies and higher grade than the three that shut down.
Anyone seen multiple computers shut down without an indication whatsoever?
