- all workstations are running Windows 7 professional.
- the server uses no-ip.org
- router dhcp
- if the user logs on at the server he is unable to access any of the folders he does not have permission too - BUT from his win7 workstation he can access anything and everthing he desires including system folders and denyed permissions

You can stop sharing a folder or drive by using the Shared Folders Microsoft Management Console (MMC) snap-in or by using a command prompt. Users connected to a shared folder are disconnected when you stop sharing it. Users may lose data if you stop sharing a folder containing an open shared file without warning. When possible, notify users before you stop sharing a folder.

To stop sharing a folder by using the Windows interface

• Open Computer Management. To do so, click Start, then right-click Computer, and then click Manage.
• If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Yes.
• In the console tree, click System Tools, then click Shared Folders, and then click Shares.
• In the details pane, right-click a shared folder, and then click Stop Sharing (this item only appears if you launched Computer Management using an account that is a member of the local Administrators group).

To stop sharing multiple files, press the CTRL key while clicking the file names, right-click any one of the selected files, and then click Stop Sharing. This removes shared network access to the selected files.
