Before carry on next step,many programs need to detect the network state.At present,because the company network architec-ture is complex and has multiple firewalls,detection of network state become difficult.This article as first introduced several old network state detection methods.Then we analyzed shortcoming of the inquiry detection mode.Finally,we proposed a windows message mecha-nism network state detection method based on IP Helper.
