I think we've all been there, your IT Support/ Infrastructure team inflict some meaningless, very frustrating, poorly explained "policy" on you and your team that irks you every time you are affected.
My current fairly trivial issues are that the IT department have reverted to the old school Start Menu. I really didn't realise how much I used the new one until they took it away.
They have also reverted to the old school Windows 2000 grey look which is quite frankly just ugly! To add to that they have also imposed a rather unnecessarily short Screen Saver time of 5 minutes, very annoying if you're flicking between remote desktop sessions!
Non trivial, they are completely unwilling to enter into a debate about using non-company laptops over our VPN.
Anyway, I'm sure you've all had more frustrating issues than me...have you?
