My RAM upgrade, so I could process huge log files without an hour of load time? Much delay; I suggested I'd just go out and buy my own RAM and install it, and got a panic'd No! Never open your computer case! They can tell, and we'll get in trouble. The upgrade got approved and install just a week after my project was complete.
So many horror stories about remote administration of critical functions. Sorry to add to the noise, I couldn't help it.
