My company has just recently bought a windows 2000 server, and I'm trying to copy all my Autocad files over to it from our old Windows NT 4.0 server. I thought just plug the new server in to the network and copy the files over and everything would be fine. WRONG!!!! Now when someone tries to open a autocad file, it says the file "is currently in use or read only. Would you like to open the file read only." I checked the read only attributes, and it's not checked. WHAT'S WRONG???????? PLEASE HELP!!!!
