Hi, Can you, and if yes, map PC 's IP and MAC addresses to a UNIX box running samba. A user who has just had his PC changed can no longer mount his directory on the UNIX box, he gets the message access denied from this location. Everyone else is ok. When he tries it on another PC it works. I have been told that a few months ago all the PC's were swapped out and users had to call UNIX support and have individual PC's IP and MAC addresses mapped to the UNIX box??? I have checked smb.conf and files it references and cannot find any ref. to specific IP addresses. Sorry if this is a bit vague but can anyone help??
