Vista Access To SharePoint Folders

In XP I am able to set up Network Place to my SharePoint folders and
access them through explorer.

When I set up a Network Location in Vista (manually) it sets up the
connection properly. However when I go to open up a document in Office
2003, I get a message saying that the document cannot be opened. After
acknowledging the message the document opens. However, if I look at
the path (enable the Web tool bar and look at the address control), it
is incorrect. The address should be https://myserver.com/... Instead
the address is http://ssl/...

Any ideas?
