I've noticed on the dashboard that the scan isn't detecting any particular OS - leaving it as unknown for most of the end points. I know these are window boxes but wonder if there is a better scan attribute that I should have on for NMAP that would improve the reporting in the scripts. Any suggestions?
And thanks for the work around on the port scanning. I wasn't receiving any data until I did that unset.
