I have a situation where there is an XP Pro machine connected to the internet via dial-up 56K modem. ICS is enabled and the other machines on the network can get access. All the machines are connected through a Linksys DSL/Cable Router. The problem is that the host machine (XP Pro) loses the ICS enabled checkbox. Sometimes the host machine is disconnected because they share that phone line with a fax machine. But whenever they reestablish a connection to the internet, ICS is not enabled. How do I save that setting?
