our master ERAS has been running for the last 8 months mostly worries free. When I got into work today I found that everything had been deleted. My policies, my parametric groups, my policy rules and lastly about 90% of my machines were deleted from the console. Why? I have no idea why this happened, or how it could have happened. When I left at 8 the night before, everything was chugging along like normal, and in perfect working order when I left. Can anybody offer ideas how or why this would happen. I need some answer's quickly.
