Questions to ask when interviewing for IT Helpdesk?

[Davepen]

Helloooo

Im going to be sitting in and playing bad cop to my managers good cop on a few interviews to try and find another helpdesk employee. We do mostly 1st and 2nd line support and was after the help of OCUK to supply me with a few good questions that I can ask potential candidates to see if their general support/PC knowledge is upto the task!

Any ideas?

We support about 2500 users, all in company, all using thin clients/desktops/laptops on citrix and locally, lots of different programs are used throughout the company, but we would not expect the candidate to have knowledge of any of them, more want to test for general support/troubleshooting skills rather than intimate technical knowledge.
