So this is my situation. I am using a mac mini running snow leopard as my file server. I have a drobo attached to the mac mini via firewire 800. The drobo has been formatted to Mac OS Extended Journaled. I created a bunch of folders on the drobo which I want to share out to my other Mac systems and two windows computers. I have a folder called Software, TV, Movies, and Public. I have SMB enabled with user accounts. On the windows computers once I input my the username and password I have no problems seeing the shared folders. The problem I am having is lets say on the software folder i set the permissions on User1 to have read only access. Well on the windows computer it seems to have full access. I can delete create etc. This goes for any shared folder. No matter what permission I set the windows computer will always have full access to the folder. I have made sure that the guest account has no access and still this seems to be a problem. As a test I connected a generic USB external hard drive (mac formated) and created the same set of permissions and I get the same result. The catch to this problem is if I create a share on the internal drive of the mac mini with read only permissions then the windows computer will only have read only access. I just switched over from PC to Mac about a year ago and I love it but I'm wondering am I missing something on on getting my drobo to have proper permissions for windows users? Thank you in advance for any suggestions.
