I am new to this position and find it's AD structure in need of a serious cleaning. There are over twice as many computer accounts as there are employees, not even taking into account servers. I'd like to be able to know which of them are still valid and which can be deleted without repercussion.
I found the tool from Joeware, OldComp, it looks pretty handy but I guess I'm just needing a bit more understanding of what it's looking at...when it searches for computers more than 90 days old, does that mean it's been 90 days since it was plugged in to the network? The reason behind this is, I don't want to inadvertently disjoin a laptop from a field office that may be on a shelf as a backup, thinking it's an "old" computer when really it's just not plugged in and being used currently. Maybe it's not worth worrying about for the rare chance that might happen though...
Anyway, if anyone knows of any other way or has a good example of how best to accomplish this I would appreciate some insight. The end result is I'd just like to be able to get rid of computer accounts no longer being used. Thanks.
