Some ISP's and IT have firewalls in place to block P2P (or clients that look like it to them) IP's. Final Fantasy XIV can appear to be a P2P client and the ISP of your School or their IT department has set up rules to block specific ports.

To correct this issue, you will need to contact your School's IT department and request they whitelist the group of ports that Final Fantasy XIV uses.

You can find the details of what needs to be whitelisted here: http://forum.square-enix.com/ffxiv/t...rror-Code-2002

Hope this helps!
