Vista GPO: Disable File Sharing

I am not able to find a GPO setting for disabling File Sharing of local folders or printers and to turn off network discovery. However there is a setting called "No computers Near me in Network Locations" in Windows XP but is there anything similar to that in Vista as well? I just dont want users to browse the internal network, thats all.

To disable file sharing or printer sharing, follow the below steps:

1. Start Network and Sharing Center.
2. Click the down arrow button next to either File Sharing or Printer Sharing.
3. To dont allow users to share files or folders, or to share printers, click Turn off file sharing or Turn on printer sharing.
4. Click Apply.
5. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.

Follow the below steps:

1. Start Group Policy Management Console (GPMC). To do so, click Start, and then in the Start Search box, type gpmc.msc.
2. In the navigation pane, open the following folders: Local Computer Policy, User Configuration, Administrative Templates, Windows Components, and Network Sharing.
3. In the details pane, double-click Prevent users from sharing files within their profile.

   • To enable the Group Policy setting, and disable the user's ability to share files, click Enabled.
   • To disable the Group Policy setting, and enable the user's ability to share files, click Disabled.
5. Click OK to save your changes.
