newbie needs help with data source

["kwgwynn" <webforumsuser@xxxxxxxxxxxxxx>]

Running Windows XP; ColdFusion 8 Developer Edition w/Microsoft Access & 
Dreamweaver CS3.

 I've installed ColdFusion, and it seems to be running okay. I know my 
Dreamweaver is good to go (been using it). Now I want to add some dynamic pages 
to my web site, so I've been trying to go through the steps from all the 
different sources I have for setting up ColdFusion to work with Access & 
Dreamweaver.

 I'm trying to define my Access database as my Data Source but it won't 
validate. I keep getting error messages associated with the username and 
password. And this is where all the different instructions I have (Adobe 
instructions for Dreamweaver or Coldfusion setup) are confusing: are the 
username/passwords (1) associated with the Access database or Coldfusion? (2) 
exactly where are they defined? (3) are they really required? But most 
importantly, HOW THE HECK DO I SET THIS BUGGER UP SO THAT I CAN MOVE ON???? 
(yes, I meant to use all caps!)
