Hi this is a follow up post to my original post in the LDDT group so please bear with me. We are running stand alone versions and it is only occurring on one of the 5 computers running 2005. Does anyone one know of any applications that don't play well with the Licensing Service? Today one of the workstations had AutoCAD 2005 shutoff instantly, fortunately only about an hour of work was lost. Checking the windows event log, it reported that the Autodesk Licensing Service had stopped. I have set the service to start automatically, and to restart on failure. It is now running again. Has anyone else had similar problems? Our firm just made the jump to 2005 from 2i, relatively painlessly (except the price tag). And thoughts would be appreciated.
