I set up file sharing like I thought I should and ran into this problem, then I checked what I did against this guide and I seem to have done it right. Thing is I can't access my bootcamp (NTFS) or second hard drive (exFAT) via OSX file sharing. I tried from two win 7 computers and one server 2008 machine, all give the same errors. When accessing the bootcamp partition (NTFS): check the spelling of the name, otherwise there might be a problem with your network. When accessing the second drive (exFAT): is not accessible, you might not have permission to access this network resource. Is this normal? I can access shared folders on the OSX volume fine. Edit: I also noticed that when I set permissions on the exFAT partition they permissions don't stay. If I limit everyone but myself and close the sharing preferences and then reopen it it will be back to what it was before I made changes. Really seems broken.
