Account Currently Disabled At first I thought this was because of the upgrade. He had done a fresh install and had copied over his entire /etc/samba directory. I thought that perhaps file formats might have changed from whatever version he had previously and that this was causing this strange error. I therefore had him remove the Samba passwords file and add the users again with "smbpasswd -a" but the problem still continued.
Samba and PDC'sPet peeve though, which has nothing particularly to do with Samba: I see far too many networks with domain controllers that never should have been set up that way. Small offices, with a handful of cooperating users, and absolutely no need for the complex security and maintenance of a PDC, and yet they get set up that way, mostly because incompetent (yes, dammit, incompetent) Windows techs don't know any other way.
Why can't my other sub-net browse the Visionfs or Samba shares?If all you want to do is ACCESS the shares, you can, even though they don't pop up in Network neighborhood. You'll need a \WINDOWS\LMHOSTS file
