FSO should already installed. Just a matter of enabling it onthe server. The others would need to download and installed on the server. That would mean finding thier website and downloading the components.
One way to find thier site, is take the name of the component from your asp pages and do a google search for them.
For example, this is the code I use to connect to an email component on my server:
Code:
Server.CreateObject("Jmail.Message")
Jmail is the name of the component. So doing a search for it would find the website where I can download the component.
There was an asp script I had that would show you which components were installed on your server, but I can't seem to find it right now.
