We have 3000 machines in our domain, at any given time 10 % could be turned off. What is the best way to get 100% accuracy and to keep an updated database of wmi information obtained from these PC's? We have the ability to read BIOS info from them now manually, or if we run a manual hyena scan, but we're looking to automate it nightly to dump info in to a database, or grab this info upon login. Thanks for any help!
