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?
