Well that got me there. Thanks.
Now I have a followup question.
When I have created network connections to SPS server in the past, I could create one to http://machinename/sites/, and I would get a folder that displays a hierarchical map of all of the areas in the portal, thus allowing me to navigate to the appropriate document library, without having to know whether the area was in C1, C2, etc.
However, on this machine, when I create the network connection, it just shows me a blank folder. Is there something else that I should be installing to get the view described above.
