As I can see here http://www.sqlstrings.com/MS-Access-connection-strings.htm
one could
Open connection to Access database located on a remote server:
“Provider=MS Remote; Remote Server=http://Your-Remote-Server-IP; Remote Provider=Microsoft.Jet.OLEDB.4.0; Data Source=c:\App1\Your_Database_Name.mdb”
Did someone try this : access MS Access DB stored on a windows or http server from a winform app ?
This requires the server to implement RDS for the MS Remote provider, which is now deprecated.
Note that this worked via a service (the OLE DB Remoting Provider) and a custom protocol (RDS), so this will not work on a linux server. It will work on a Windows server which has the MS Remote MDAC provider installed. However, it is obsolete technology, and would be better implemented using a more modern technique.
