I usually hard code the page. I am not saying it is the best thing but that is what I do and it works. I'd say use the OLEDB connect string and just hard code the path like so:
<% strConnect = Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\databases\sbdc.mdb;Persist Security Info=False %>
You will need to set the path to where you have the actual DB and it is the path on the server (physical), not the web path.
