Need help with a script on IIS 7 to verify the Application pools

Hi,

 Could somebody help me with a script  (I am very new to scripting) to find the status of the App pools of different servers .

We have 6 front end servers (on which websites are hosted) and 6 servers on .Net application services are hosted. We need to do the health check of

all the Application pools hosted on those servers.Is there any way or a script we can write to do those. All the websites and .Net services are hosted

on IIS 7.

Script :VBScript or a powershell preferrable VB.

Thanks
