I'll try to be succinct here - if you need background info, I'll be happy to supply it. We are opening a small branch office. The branch office will be staffed by people from our main office, so when they are not here they will be there and vice versa. So - we would like to keep all of the drawing files on our server at the main office. We will be VPN-ing in from the branch office for AutoCAD files (would have preferred Terminal Server, but you know the score). In VPN-ing in, I would really like to not have to work with the files over the WAN, but to download them in the morning and then upload them at night when you are done for the day. However, in doing so, the drawings will still look as if they are accessible in the main office, and I do not want someone going in to the same file and working on it while someone else is working on it in the branch office. We could solve the issue by actually moving the whole drawing file back and forth, but if people in the main office still need to refer to it, it would not be there. What I would ideally like is some sort of add-on piece of software that allows us to choose to check-out drawings that will automatically lock them down as read-only until they are checked back in. I swear there are such programs, but cannot remember any of them, now that I need them. Any suggestions? Thanks - Susan
