Default Behavior

Internet Connection Sharing (ICS) is a Win32 service. In Windows 8 it is disabled and therefore it won't start under any conditions. When the Internet Connection Sharing (ICS) service is started, it runs as LocalSystem in a process of svchost.exe, sharing it with other services. If Internet Connection Sharing (ICS) fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the SharedAccess service hasn't been started.
