I'm no expert in this area, but I'd nicely suggest what you just said to him.
Does the supervisor know computer well? Or is he just installing them?
No, they do not know computers in detail. They figure that since the wifi signal is available, with the
password, they have access to the Internet. However, this is a school network is divided by curriculums and
the age of the students. So some computers use peer to peer where others are just separate and are used
to access the Internet and then the more important ones access an SQL database on three (3) servers.
So the right configuration on these is critical along with security such as making sure the students have
a standard user account and not an Administrative account among other settings. Also include is disabling
social networks on all of the machines and remote software to make sure a connection can be established
when troubleshooting slight to mid severe problems with a particular machine on the network.
