Normally the addresses are (works for both staff and students with a substitution of s1234567 with your my.UQ username):
All Campuses except Ipswich students - \\soefile\s1234567But that wouldn't work in the Go->Connect to Server Dialog. What does work (at least for St. Lucia, I'm not an Ipswich or Gatton student so I can't confirm it for those campuses) is:
Ipswich Campus students - \\uqistudent\s1234567
Gatton campus students - \\UQGfile\s1234567$
smb://soefile.uq.edu.au/uqxxxxx or smb://soefile.uq.edu.au/s1234567
But you can't browse the "local" network that you are VPNed into for some peculiar reason. Also, you can then save that connection as a shortcut to your desktop by dragging the network icon and name from the top of the finder window to the desktop (or any folder for that matter), but for some reason not to the sidebar.
