We're running a small SBS 2003 network with 5 users and need to enhance the security of the directories on the server. We have one drive F: with two folders, Common and Private. The common folder has subfolders where everyone can read and write to the files and the Private folder is restricted to administrators. A user is either a member of Users or Administrators. If we deny access to F: for Users how are they then allowed to read and write to files in the Common folder. I know my issue is rather rudimentary but I've never had a strong grasp of user rights and permissions. Any help would be greatly appreciated. Thanks in advance. Michael.
