Mapping Network Location to website results in empty folder win 7

We used to map a network location an http site in Windows XP. Worked well, but under Windows 7 when we map the same location we show an empty folder and it should contain all the links from the site. I did notice that when we tried this on a different XP box we were prompted for the user ID and Password to login to the share (makes sense to me... ) but there was no prompt in Windows 7 - instead we just get "This Folder Is Empty"

Did I miss something? We can access the website in IE... did not try to access the share using the computer name instead of the website... could try that.... however they use the mapping as above because they still use FrontPage to administer the site and this method provides the mappings etc that FrontPage likes to have.

Worked on this for a bit today. Can auth to the website. Can auth to Front Page to update the site. But through Win 7 I am unable to auth to map a drive, in actual fact I believe I do get authorized but instead of being take to the share I am put at the root ...davWWWROOT.... not the share and of course I get Folder Empty. I believe this to be an AUTH issue ... I have opened a case with MS and will post once I know the answer.
