I work at a service desk for an automotive supplier.
We've once hab out entire mobile phone system crash and for whatever reason, it won't let the phones connect, if there are more than 50 phones trying to connect at the same time. Kind of a problem if there are 400+ phones trying to connect.
My colleagues showed me what to do in order to get one phone to connect to our system.
It was basically: enter some invalid data on out webinterface, save, enter the correct data again and safe again.

It was too stupid for me. So i hacked an AutoIt script together in about 15 minutes, and let it run for the next half an hour. Showed it to my colleagues, they were excited and I went and got a coffee.
