Hi, I'm trying to re-install my Linux box and I don't know which files I have to backup. What do I have to backup beside /etc/passwd /etc/samba/ BTW, my Samba is PDC and I'm running Win2K & WinXP machines so I have to backup the SID file (so I won't have to re-join all the machines to the domain), but I don't know which file it is. Is there a way to re-install the whole Linux and Samba and still have the same domain controller?
