One of my clients has a 2003 Standard Edition Server. Around a month ago, it shut itself off. After restart it, the server stayed up and running for around a month. This week, the server shut itself off 3 times 2 days aga and turned off again this evening. I stop the UPS service running on the server (I thought maybe the UPS was shutting down the server. I guess it don't work.
Does anyone have any suggest to why the server shuts itself off, not restart, but shutdown.
