I must say im surprised to see someone learning classic ASP. You do realize we officially called old dinosaurs? Anyhow to help a fellow dinosaur...
Does installing sp3 on XP upgrade IIS 6 to IIS 7? Dont focus on sp3, its the version of IIS you need to focus on. by default 7 has ASP disabled by default. It is well documented the three or four things you ned to do to get it running. You need to:
turn on the ASP feature on and create a role
create classic ASP application pool
enable parent paths
send error to bowser
turn off freindly IE errors
All about it:
