We have a strange problem with Solidworks 2007 SP4, so i canopen afile from a network drive, make a little change and save itback.If i change more, then i cant save it to the network drive(alsonot save as on this drive). I can save it local and it worksfine.With save-as he writes something on the net-drive, but SW cantopenit. I try different users (the same) and on another networkdriveit seems to work. The server s an Win2003 SP1 withactivedirectory. On the second machine i have no problem....SolidworksAdministration
