Gathering IIS 6 website properties

[hurtsmyhead]

Hi all,

I was put on an IIS migration project where we have to discover, then migrate the applications (websites) on several thousand Windows 2003/IIS 6.0 servers. I've been asked to put together a PowerShell script that would do the initial discovery, and I am definitely not a scripter of any sort. I found the below script on Technet, and by the description it seems to do a lot of what I need, plus some things I don't need...but it doesn't seem to work--it doesn't produce any output. I'm trying to learn PowerShell but I'm a complete newbie and I'm a long long way from having the ability to figure this out. I think the project will be over by the time I get this thing going.

I need the server name, the website name, and the app pool and asp.net version associated with that site. I need the output to provide one row of information per website, something like this if a server was hosting three websites:

server1 website1 DefaultAppPool 2.0.50727
server1 website2 AppPool2 1.1
server1 website3 AppPool3 2.0.50727

Can someone take a look at this script and at least tell me if you see any major issues with it, and maybe give me some tips?

Thanks
