How To Prevent Windows 7 Local Account Users From Changing Internet Settings
You may know that Windows 7 comes with an
enhanced UAC (User Account Control) feature that regulates the access to user
account profile folders, allowing local account holders to separately save
their application settings, files and library folders, including Music,
Documents, Videos, Pictures, etc. It doesn’t provide a convenient option to
prevent local account holders from enforcing Windows 7 system-wide settings.
For example, local user accounts, including standard account, can change the
default screen resolution, modify DHCP settings (including primary &
alternate DNS server address), default gateway and PC local IP. Many times, it
happens that local account users change the DHCP settings while diagnosing
internet connectivity issues, and modify the correct gateway, IP address and
DNS server address. If you hold an administrator account on your home PC, you
can prevent others from changing these settings. This post shows a simple way
to prevent others from accessing internet/network configuration settings.
Since this method
requires changing Windows default user account access options, you need to log
into Windows as an administrator for restricting access to Network Connection Properties dialog. Using the
Microsoft Management Console snap-in namely Local Group Policy Editor,
you can change the default settings of numerous local group policy objects. To
begin, type group policy or gpedit.msc in Start search and hit enter to
open Local Group Policy Editor.
The Local Computer
Policy is divided into two broad categories – Computer Configuration and User
Configuration. First off, expand User Configuration,
and then open Administrative Templates. Once opened,
navigate to Network, and then click Network Connections to
view all the related settings in main window. Now, find Prohibit access to properties of components of a LAN
connection setting, right-click it to select Edit option.
It will show the default
settings in a separate dialog. Now, check Enabled button,
which is present adjacent to comment box. Once done, click OK.
Enabling this setting
will prevent standard account holders from accessing Network Connections Property dialog. However, if you want
to disable the Properties button, open Prohibit access to properties of a LAN connection setting
from Local Group Policy main window, and then check Enabled button to completely disable the
Properties button of internet connection.
When standard account holder attempts to access
the Network Connection Dialog, it will deny the access to connection properties
dialog.
In case you’ve
enabled prohibit access to properties of LAN connection option,
standard user account holders will see an inactive (greyed-out) Properties
button.
These settings will help
you prevent other account holders of your home PC from changing the internet
connection settings. It must be noted that local account users will still be
able to connect to internet/local network, view the details of active
connection from Network Connection Details dialog,
and diagnose the internet connectivity issues.
