I found out something on my clients network recently regarding C drive root permissions. My client works with sensitive data and if a user is NOT on the domain then they are not allowed to view ANYTHING on the network. I found out this week if a user connects to the network via the local lan then they are able to view files on the C drive if they enter \\servername\c$ even if they are not administrator. I need to change permissions that ONLY domain users are alllowed to view the network files, if a user is not on a network then they are not allowed to view anything. I want to restrict all users from accessing the root on the C drive. Please help! :)
Please see screenshot attached of current c drive permissions.
