I have a client with NAV Corporate Edition. When I click on About the description comes back server/client gold (mfg only) There are 4 computers networked together but there is no server. They were part of a domain a couple of years ago however that has not been the case since the 4 machines were reformatted, XPP reinstalled along with NAVCE from the backup copy on one of the machines It runs live update and says that everything is up to date. Question is, isn't there an annual subscription to this? If so, they have not paid for anything. I suspect that they really don't have AV protection at all. Might I be correct?
