data access page

I have developed a Data access page in access 2002.
I want to deploy it on my webserver ( IIS 5.1).
However i get an error with the connection string to the database.
In the source of my data access page I have replaced the line,

Data source = C:\root\dap.mdb with

Data source = http://123.23.12.31/dap.mdb ( just some ip address )

I have set the root directory of the webserver to c:\root.

But i get an error that this is not a valid filename. Although the page
loads, I Don't
connect to the database file.
I have set the UseRemotePRovider to true, for three-tier access.

can someone help me please.
