Good morning, we got three domain controllers and one exchange running on Windows Server 2003, yesterday there was a power outage for x number of hours, all of them are plugged into UPS, but it could olny hold power for 45 minutes. And I was not able to properly shut down each servers. now, every servers are powered on by itself. I did not do anything yet but to log in to each servers and they are working, what potential risks/damages might have happened during the power outage/improper shutdowns? Also we got Red Hat Linux 10 server that was not properly shutdown,. What should I do? Thanks a lot. How am I gonna know when the power came back up? thorugh event logs?
