I've been having a problem with the Windows Firewall/Internet Connection Sharing (ICS) service on my ISA server. I'm fully aware that this service is not needed when ISA is install. However the service keeps setting itself to start automatically after a period of time, even when I have disabled it. This isn't normally a problem unless the server restarts and ICS wants to start thus not allowing ISA to work, however I am normally in the office to sort this. But last week I was out of the office and had to explain how to fix this problem. Therefore does anyone know for a more permanent solution to our problem?
