Default Behavior

Network Connection Broker is a Win32 service. In Windows 8 it will not be started until the user starts it. When the Network Connection Broker service is started, it runs as LocalSystem in a process of svchost.exe, sharing it with other services. If Network Connection Broker 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 NcbService service hasn't been started.
