I have set up a network with about 20 computers all running windows 7. Any file I share is accessible to all the other computers on the network. My aim is actually to share files with specific computers on the network; not all. How do I achieve that?
Remove "Everyone" and "Authenticated Users" from the permissions and add only the user accounts that you want to be able to manipulate the files. Don't forget to add yourself will full control and add write permissions if the user needs them, or else you'll be up sh** creek.
