Interview Question Help

As part of an interview process for a Junior Network Administrator position I've been asked to give an example of a particular difficult problem I've had to troubleshoot and explain the steps I took to resolve it.
Although I can think of many difficult roles I've been given or tight dealines to hit, I can't think of a single individual task I've encountered that stands out more than another. It's also difficult to think of exactly what steps I took for an idividual task last week never mind over the past 10 years.
I'd really appreciate hearing everyone's opinion on which area of networking I should take my answer from. I've started writing it a few times but every example I come up with seems very uninspiring when compared to other areas of my career.
I have to this sometime this evening so it's a lot to ask of people but I'd really appreciate any thoughts anyone may have.
Thank you.

I've sent an answer back to the company that includes a little of every single suggestion.
The example i used saved the company money, involved me having the building kept open late until I'd resolved it and ensured it never happened again. Unfortunately. because I didn't want the answer to be a chore to read, on paper it didn't look as big a struggle as is was. If I can reach the full interview stage I'm sure I can elaborate then.
Thank you everyone for your help. It's given me a far better chance of a reply and left me a few hours to prepare for another interview tomorrow.
Thanks again.
