Instead of Provider=... use

Driver={Microsoft Access Driver (*.MDB)};

What server OS? The error you listed may be caused if you are trying to put an Access db on a *nix box using chilisoft for asp.

If you're on a windows server you may need to update your MDAC, you can download the latest from http://www.microsoft.com/data
