Windows 10: Disable Internet Connection Sharing with Group Policy

Internet Connection Sharing (ICS) is a Windows service that enables a computer to share its internet connection with other computers on a LAN. This computer serves a gateway device, meaning that all traffic between other computers and the internet go through this computer.

Users can turn on the feature from the immersive control panel:

Please note that it can be a critical security issue in your environment. So you can easily disable this feature using Group Policy.



Open Group Policy Management Editor and navigate to:

  • Local Computer Policy,
  • Computer Configuration,
  • Administrative Templates,
  • Network, and Network Connections.
  • Double-click “Prohibit use of Internet Connection Sharing on your DNS domain network”.
  • To enable the Group Policy setting, and disable ICS, click Enabled.
  • Click OK to save your changes.
