.NET - What is the best library for inspecting and controling Windows Services? -

I need a set of Windows service monitors and controls that are running on a local machine or remotely. I've heard of WMI and ADSI and the first thing I want to do is I want to. Before going deep into it, I just want to see if I am going in the right direction?

edit Additional information: I also need to inspect SQL jobs and IIS examples, so I think I should do the same I want.

You may want to see the ServiceController class.
