Hi to everyone! I need to solve this problem. There is a file example.xls who is used by a client on Windows XP system. This file is in my Ubuntu server and shared through samba to 7 machines on a small network. When a XP system hangs and the file is not closed clearly this file get locked and i need to restart samba for unlock this for can use (and edit) this file again. What's wrong ? Best regards. Emiliano.
