The Technical School has different computers
- for teachers
- for students
- library computers
1 year ago everything worked, but now, when the cable is connected, RDP and a network drive work, but there is NO Internet.
I have already tried the Internet config on the machine - it did not help
. To score the specified Internet config, which was in the computer - did not help either.
What's the matter?! What to do???

1) MAC
2) The proxy is registered in the settings
3) There is no default route - the admin manually prescribes via route

Filtering by MAC address?
Set network card MAC of a computer disconnected from the network?

Ask the person who is in charge of this. There can be anything, up to restrictions on the MAC address.

Most likely there is a transparent proxy server - and port 80 (www) is taxied to it (with IP authorization). Or there is a simple proxy server - but then all ports would be closed. If the disk and RDP work, then the VPN will also work. In any case, if you do not "steal the Internet" contact the system specialists for the settings.

I, as a network administrator, would have acted simply. I would make several VLANs on the network (for the library, students, teachers, cleaners, alchemists, cosmologists, green men, milkmaids and shepherds). I would install an authorization server like FreeRadius. On switches and wifi access points, I would set up 802.1x authorization. I would distribute logins / passwords to the network to all employees.
And I let all the other, unauthorized studios into the guest VLAN, where I would turn everything off and leave RDP and a network drive for uploading dissertations to teachers.
Actually, as they write in one operating system: "If you have problems with the network, contact your network administrator."
PS. And it looks like you have a normal network engineer at the institute (oops, technical school)!
