I moved this from the Report Center section of the forum to here. Please keep in mind that the Report Center is only for posting finished reports, not questions. To answer your question: you can add
this Active Directory group report to your Lansweeper installation by following
these instructions and then filter the group name within the report results to see users belonging to a specific group. Make sure your AD groups are scanned first. Instructions for scanning both users and groups can be found
here.
