My client (my father) thinks there may be cost savings by running AutoCAD in a network environment. His small office consists of 4 users. We guesstimate only 2 user would be running AutoCAD at any one time. I gather from these posts, the technology used is the Network License Manager. A few basic questions to start with: What are the typical costs (UK £Stg) for implementing this? Must all clients be running the same version of AutoCAD? What if one client is a laptop user, can he use the program offline (ie from home) without authentication by the server. Many thanks for any help. Keith
