MS Access and Password Error

I'm running ColdFusion MX 7 and Access 2003 on Win 2K. I've inherited a
ColdFusion 6 (or before) site that I'm trying to get up and running. In
Dreamweaver MX 2004, when I try to bind my "request.dsn" variable to the
database (the same database used for "application.dsn"), I get an MM_error
message for my user_password variable:

com.inzoom.adojni.ComException ...

I've checked all the angles I can think of, but I can't get CF to make the
connection for that recordset. Four other recordsets that depend on the same
request.dsn variable hook up just fine.

What am I missing?

Thanks!
