My company is undergoing an audit right now. We probably hold more AutoCAD licenses than any other company in Canada, so they like to watch us like a hawk. We used to be terrible for software licensing (I think only about 30% of our software was licensed two years ago). Now we keep accurate records and nobody installs anything without the net admins knowing about it. It cost us a lot to get legal, but I am ever glad that we are. We just show our records to the auditors and tell them to take a hike.
