iMovie import from server error -43
I have a room of macbooks that have had no problems with imovie imports using local user profiles where the user movie file are on the local machine. Recently I have moved the increasing users to server X and have had little issue except.....
I can no longer import files into imovie I get the error:
"Copy Failed
This file could not be copied:
/Network/Servers/server.xxxx.local/Users/UserName/Desktop/movie.mov"
I have had no probelm with the same file locally stored so this must be a server permissions error. Does anyone know where the permissions can be found, I suspect, on the server?
Desperate........
Thanks
