At my school, there are macs for several departments, the art, music and media departments. while i was doing music gcse (im 16 btw) i noticed that the music techer, even though he knew alot about macs, he was having problems with his mac pro.
The problem was that every time he went into itunes, and every time he chose a song or playlist, it asked him for a username and password due to a proxy error. they rang up the IT department, ask asked them to help, as they were the ones who does all the computer stuff, so they came over, and had a look. they were completely baffled, they had no clue what was going wrong and so they called Apple for help. they described the problem to them, and like the IT department, they didn't know what to do.
now, i have a macbook, but i can't connect the the school internet using ethernet, without changing some proxies, to my schools one so i had some experience with proxies. i asked the music teacher if i could try and fix it, and he said he would let me try, but didn't think i'd fix it, so i set off to work.
first thing i did was recreate the problem, and like he was saying, it was a proxy error. so i went to safari, preferences, ethernet settings, change proxies and had a look there. turns out he was not using a proxy to connect, so i changed the proxies, and then tested for the problem, and it now doesn't say there is a proxy error, so i, a child of 16, who is lazy about work, had fixed a problem that the IT department and Apple could not fix!!
