If you are struggling to connect to the school network and are using older operating systems like XP, you can try the following:-
First thing is first – Make sure you are running XP SP3 or higher. Anything lower than this and we can not support you, you also will be prone to more attacks on the internet.
Follow everything listed and it should fix your issues.
Windows 7 or 8 users should have no issues connecting, but if you do, follow the first part of the article above and make sure addons for terminal services are enabled then refresh your page on the school site.
