Error 3194, Error 21 and Error 1013 I finally found a few ways to resolve this after searching on http://anditsfixed.blogspot.com/2012/10/solved-itunes-error-3194-error-21-and.html Apple's support page and other sites. I also came to the conclusion that the error 3194 in iTunes and the other errors are quite common and luckily quite simple to isolate http://forum.gsmhosting.com/vbb/f852/unknown-error-occured-21-a-1183045/ to then resolve.
