Abstract
A network system comprises a first communication device and a second communication device. When device failure caused in the first communication device, the first communication device generates the device failure information and transmits the device failure information to the second communication device. The second communication device receives the device failure information, and memorizes the device failure information, and makes a display unit display the device failure information.
