Setting up ODE DB connection

hi,
im trying to Set up ODE DB connection, i am running windows 2k and i have mdac 2.8 installed and all that stuff ya know, i have 1 file dns 1 user and 1 system databases configured in my odbc manager, all of them go to the same database
D:\import\main.mdb
its all in Access 2000

all of the odbc databases are configured to
login= admin
pass = password

now when trying to create a connection within dreamweaver i click on templates and choose ms access 2000 jet driver, and then it askes me for the parameters, i have them like this
Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=[maindb];
User ID=[admin];
Password=[password];

now my user dns is named maindb my file dns is odbcmaindb.dsn saved in D:\import\ and my system dns is named sysmaindata non of the odbc connections are pointing to a system.wmd only to
D:\import\main.mdb

when trying to test the connection in dreamweaver it says user name or password invalid, now
i have a couple NT users on my comp ive tried their logins and all of mine, nothing seems to work
i really need to make this connection is ASP.net can any one help me out what am i doing rong?
