Solution

This is the errors/problems we encounter when using multi-computer client PC:

1) The VLC media player crashing on the Stream PC
2) Between the two or more computer were unable to ping
3) That the VLC media player between the Our Allocated Computer is version 1.12 while our laptop's is version 1.14

-----Below is what we try that couldn't work-----
1) & 2)
--> We close the VLC media player and start the VLC media player again but the problems still appear.
--> We restarted our computers but the problem still occur
3)
--> We uninstalled the VLC media player version 1.12 at our allocated computer to VLC media player version 1.14 but we do not have the administrative rights to access the computer

-----Below is the Solution that our group use to solve it.-----
To solve the above three errors/problems we decided to reformat our allocated computers to able us to install the VLC media player version 1.14. After that everything are able to work without any errors/problems.
