The H4S terminal can support multi-server broadcast from the netpoint2.4 version. You only need to modify the IP address behind the ServerEx parameter of the netpoint.ini configuration file in the netpoint installation directory from the server where the teacher machine is located.
There are a total of 50 H4S terminals in the classroom, of which 25 H4S (including 1 teacher machine, 24 students ) on Server A (IP address is 192.168.0.142), and the remaining 25 H4S on Server B (IP address is 192.168.0.143). In order to broadcast the desktop of the teacher's machine to the student machines on the two servers, you need to follow the below instructions:
Log in to Server B and open the NetPoint.ini file in C:\Program Files(x86)\NetPoint\ with Notepad, as shown below.
Remove the ";" in front of ";ServerEx", the IP address after the equal sign is changed to the address of Server A where the teacher machine is located: 192.168.0.142, and finally save the changes and restart Server B.
