First off let me say I have gotten file sharing working between Windows 7 and Leopard/Snow Leopard. I also setup have my shared folders password protected on my Windows 7 machine and get prompted for a password when logging on from any of my Macs. My problems are: 1. Windows 7 will not prompt for a User name and password when logging into my Leopard/Snow Leopard shared folders. So I have to leave them set for Read/Write access to everyone. Is there a networking entry that can be changed in "Local Security Policy" to get Windows 7 to prompt for a user name and password when logging onto shared folders? 2. On Leopard/Snow Leopard custom shared folders the User entry for "Everyone" only allows me to select "Read Only" or "Read & Write" while "Write Only" and "No Access" are greyed out. Nor can I delete the Everyone entry. How can I force the "No Access" selection or preferably delete the "Everyone" entry? I only want these folders to be accessible by select users that have the correct user name and password. Edit: Just as an update. Post #8 lists how to get file sharing working between Windows 7 and Snow Leopard. I can confirm that the same procedure works with Windows 8 Pro and at least to Mountain Lion. Some of the wording may have varied a little in later versions of OS X but essentially the settings you want to use are the same.
