I have been fighting with Installing IIS for a day or so now.  I was getting a very generic error regarding that the setup failed to install the components.  There was no real detail as to what the problem was.

Well, I finally figured it out.  You have to install the .Net Framework 3 before installing IIS or IIS won’t install.

It makes sense, but I figured Vista would be smart enough to figure that out.  Guess not.
