What's the easiest was to report upon the absence of installed software? If I have 5000 servers, I want to know which ones are missing application xyz. The only method I've devised is a custom report with 2 columns - one column for every server that has application xyz installed and one column that simply lists every server. I export the results into Excel to find the server names that only appear once.
Is there an easier way to obtain this info without involving Excel?
Absence of a software? Which one? Seems kind of odd to want a report on that. Are you trying to get a report of where you have A/V missing or something? When I want a report of all my servers that do have something installed (for example MS Office in the attached screenshot) I report on all nodes then filter by name = Microsoft Word, Excel, etc.
