We have a user that borrowed a SolidWorks license to his laptop. We have 9 licenses and when he borrowed it three became locked by his User/computer. Based on some reading that the license gets locked via the network adaptor I have two theories but can't really check much because I don't have admin access to the server and he is traveling and not responding. 1) He may have checked this license out either at the office while connected by both wired and wireless, which would account for two. 2) He may have also checked it out via a VPN which because of the number of devices may have locked two or more.
Additionally, his computer shows only one borrowed license with an earlier return date. So that's another level of confusion.
