Determines whether users can change the properties of a LAN connection. This setting determines whether the Properties menu item is enabled, and thus, whether the Local Area Connection Properties dialog box is available to users. If you enable this setting (and enable the Enable Network Connections settings for Administrators setting), the Properties menu items are disabled for all users, and users cannot open the Local Area Connection Properties dialog box. Important: If the Enable Network Connections settings for Administrators is disabled or not configured, this setting will not apply to administrators on post-Windows 2000 computers. If you disable this setting or do not configure it, a Properties menu item appears when users right-click the icon representing a LAN connection. Also, when users select the connection, Properties is enabled on the File menu. Note: This setting takes precedence over settings that manipulate the availability of features inside the Local Area Connection Properties dialog box. If this setting is enabled, nothing within the properties dialog box for a LAN connection is available to users. Note: Nonadministrators have the right to view the properties dialog box for a connection but not to make changes, regardless of this setting. Fix: (1) GPO: User Configuration\Administrative Templates\Network\Network Connections!Prohibit access to properties of a LAN connection (2) REG: HKEY_USERS\Software\Policies\Microsoft\Windows\Network Connections!NC_LanProperties
