Files Created via FTP not accessible to other users

Thank you both arjoseph and StephenB for your replies. arjoseph, I tried all the steps you suggested multiple times, and was able to fix the existifng files, but each new upload would be unaccesible.

After I posted, I realized the same thing was happening not only to FTP'd to files but also to any other files I copied through normal Windows Explorer copies - they remained visable, but not accessible to read-only users. This was with the "Automatically set permissions on new files and folders" under Advance CIFS Permissions. I was banging my head over and over (hours) with every possible combinations of settings on the CIFS settings page, reboots, without resolution.

RESOLVED:

I created a new share, and moved everything over to the new share - which was quite a pain because there was about 500GB of data. The new share works fine with both CIFS and FTP. Still don't know the root cause as to why the original 'media' share that I had been using for a couple of years became unusable.

Thanks,
Tom
