DavWWWRoot

It is telling Windows to connect using the WebDAV protocol.  The @SSL tells the WebDAV protocol to use HTTPS (port 443 vs port 80 for non SSL traffic).

Here is the issue explained by the user:

I have tons of spreadsheets on the portal that I use to analyze contract data.  I must frequently link data from sheet to sheet so that as I make changes in one sheet the changes feed into others.  In the last day or so, I’ve noticed a problem with the links.  When I link to another open spreadsheet, the link looks fine and works fine (updates when changes are made in the other sheet).  But as soon as I close one or the other of the spreadsheets, the link is replaced with one that contains the @SSL and DavWWWRoot.  Apparently this causes the link to go dead because it no longer updates from the linked spreadsheet, even if I open them both back up.  

It is a Windows 7 machine. He created shortcuts to files on the SharPoint Portal. The files are ok when he opens them from the portal. But when opens them from the shortcuts it shows the @SSL\DavWWWRoot in the filename and is unable to link to other spreadsheets. Is this a Windows 7 issue? Ideas?
