I need to perform a task where I can get a few information about the server the web application(I'm going to make an ActiveX dll to use these commands/API)

I need to determine the web properties that are set on IIS, I need to know the state of the Web Services
and I need to know the version of NT and IIS, and the Service packs (I know an API to get the OS version, but the rest I'm having troble with)

after the server information, I need to be able to get the ODBC settings, like the list of DSN, and the details for each.

At the moment All I have is a ASP that looks like Windows explorer a bit, and I have it where on the browser, you can click the directorys and change, and being able to see the Version information for the ActiveX exe, ocx, and dlls

for the curious fews, I am trying to write a Dianostic page to accompany our larger web application, so if they ever have a prob, we dont need to go down there, or we dont need to call them and ask them a bunch of questions.
