Solaris 11.3 IPS package repo? Cannot copy files

When I try out Solaris 11.3 IPS package repo, it is not possible to download and install software. Why is that? Is the 11.3 repo closed?

And another question: I have a Windows NAS and I can copy files from Solaris to the NAS. And I can also copy the file back to Solaris. However, I can not copy a Windows file to Solaris. Could the problem be something that Windows files have no write permissions on Solaris?
