Miss_Dee - really??? I would have thought that desktop support was quite a specified skill...
Got my job titles mixed up. Desktop support is level 2. Help desk (or service desk) is level 1 which often requires no experience. People having problems call help desk in the first instance where they follow a script so no prior knowledge is needed cause it's all there. If help desk can't solve the problem it then gets referred to desktop support. According to DF who works in IT, if you have half a brain you can move from help desk to desktop fairly quickly too.
