I have a network of 3 OS X & 3 XP machines. I use Samba for file sharing and have set up groups in OS X and workgroups in Samba. I am trying to share an MYOB file across multiple Macs Using XP as the file server. The permissions that show up on OSX show up as group "wheel" and read only. I need the group to show up as the workgroup with rwx permissions. Any ideas on how to fix this?
