Hi There!!
The Samba is runnng perfectly in my Quadra 650, but Windows don't recognize the permission, or something else.
I see the "Quadra650" in Neib Network window. But when i click to map the computer, it says:
\\Quadra650 is not acessible - The remote computer is not available.
Something wrong?
"QUIZ" is my workgroup My smb.conf is:
