I suggest you search this forum, but to date I have NOT found a way to remotely access 'Access' DBs. Once, long ago, I wrote a script which ran on the same machine as the Access DB (with a web server). The script was sort of a generalize DB access script which I could call from the 'real' web server to fetch results. It was slow, but it worked. But don't ask me to post the code (I don't have it or own it).
If you do find a way to remotely access MDBs, please post it here.
