Fine. I'll concede that you are an office admin. The IT people who do more than that, though, are not. A person who does easy stuff with desktops like you describe is doing something users should know how to do. The person who made that default image probably knows more. The person who configured the network and got everybody online while monitoring their machines for security incidents knows more. The person who ensures the necessary servers are available so work can continue know more. These things are clearly IT. We can draw a line between IT and software development if you like and still acknowledge that there are roles on the IT side requiring more advanced skills.
