I work in a small (6 employee) web/design shop. We have a file server that we use to store large design documents (photoshop files, flash source files, indesign etc) and other work-in-progress. The server is just a basic windows machine with some beefy hard drives and file sharing enabled. (We're in the process of moving to a solution using FreeNAS instead).
The owner/lead designer of the company loves to work directly on the files on the server (as opposed to making a local copy and working on that). This of course leads to all sorts of awesome file corruption and file access issues. I've shown him the support articles on Adobe's website explaining that his workflow is a terrible idea. He remains convinced that the problem is actually just a 'permissions issue' and if we just switch to using NFS instead of Windows shares/Samba, everything will be fine.
My question is: Can you recommend any other resources that might help me change his mind? Alternately, can you recommend any resources that might help to change my mind? He uses a Mac, so if there is anything specific to that OS, it might carry more weight than general information.
Currently I know about:
