Yes, I've seen that, but I never knew what it meant, and so it didn't give me confidence in the installation. (Did I make the right choice? How would I know if I didn't?)

We don't have a netinstaller, so a connection to CRAN is not necessary. I would guess that a large number of people installing R don't have a net connection at the time, because a lot of students get it on a CD.

It seems to me that if internet2 works at all, it should always be used, whether necessary or not. (It might be that your machine is behind a firewall sometimes, but not always: but if you've got the required library installed, you probably won't lose it.)

Maybe internet2 should be the default now. I'd guess nowadays most Windows systems would support it.

Does anyone know if there are any disadvantages to using the WinINet functions via internet2.dll instead of the WinSock functions via internet.dll?
