invalid UNC path with openrowset

Question

I've created a folder called Public off the root of my C:\drive and have shared it with "Everyone". I've also given NETWORK SERVICE read rights. But when I issue the following query in SQL Server 2008-R2, the error is that "\\FOO\public\my.csv" is not a valid path:

SELECT * 
FROM OPENROWSET (
  'Microsoft.ACE.OLEDB.12.0', 
    'Text;Database=\\FOO\public\my.csv; ', 
    'SELECT * from my.csv'
    )

The 64-bit driver of ACE is installed. I'm on Windows 7 x64. It's a 64-bit version of SQL Server. My PC's machine name is "FOO". It doesn't work with a simple c:\public path either.

OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "(null)" returned message "'\FOO\public\my.csv' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.".

I've configured the server so:

exec sp_configure 'show advanced options', 1
RECONFIGURE;
exec sp_configure 'Ad Hoc Distributed Queries', 1
RECONFIGURE;

What else to check? Thanks

The problem is fixed. The Database should point only to the folder and not include the file:

        'Text;Database=\\FOO\public; '
