I don't know if it helps, but I;ve just done a clean install of ClearOS 6.9 (because 7 doesn't recognise one of my NICs) and had the same problem I;ve had with every ClearOS install l've done for the last few years - the smb service doesn't start when the machine is booted. I've fixed it each time by editing one of the init files to do a "service smb start" (can't remember which one - it's actually a job for tomorrow for me) and then it works fine.
