Out of the blue, I got a question from my blog yesterday about Termincal Server licensing reporting. I may as well dust off the old bloggers cap and attempt to spark some discussion.
    Paraphrased, the person who asked the question wants to find a way to create a report to show how many licenses they have purchased and issued, ultimately to create a chart. They say they have tried the command 'lsreport' but it's only helped a little. and they would like to know is it possible to do this with WMI scripting? Any other tools out there?
    Personally, first of all, I've never needed to report TS licenses before. Second, therefore I don't know of any tools other than lsreport, which I've never actually used in a real-world scenario before. Therefore, my first inclination would be to create my own tool if lsreport didn't provide what I was looking for. In about an hour of researching my intial feel is that lsreport should be able to be leveraged. The big question is what do you want your chart to look like and be used for?
