If Internet Connection Sharing (ICS) is not working or has stopped working after a Windows 10 computer reboot or Service restart, then this post will be able to help you remediate the problem.

Internet Connection Sharing is a method for connecting multiple computers in a LAN to the Internet through a single connection and a single IP address. ICS typically uses NAT technologies to achieve this and works with most connection technologies, including DSL, cable, ISDN, dial-up, and satellite. The device with the modem or broadband interface that establishes the connection to the Internet is called the ICS host, or gateway while the other devices that connect to the Internet via the network and the ICS host are called ICS clients.
If the ICS host fails, then all of the ICS clients lose their Internet connection.
