Running a report does not trigger a scan of the machines contained within the report. A report only queries what is already in your database. The information stored in your database will only be up-to-date if your machines have recently and successfully been scanned.
Scans are set up through the Lansweeper web console or triggered from your client machines with the LsPush scanning agent. If you are trying to scan machines in specific reports on a scheduled basis, you could do so with
Asset Collection Scanning.
Lansweeper 6.0 will allow you to have report results automatically copied to a folder by the way. We're currently in the final stages of internal alpha testing for 6.0. If you haven't already, contact support@lansweeper.com to be added to our list of beta testers. You'll be notified via email as soon as the beta becomes available.
