connection problem

Hello,

I try with any kind of success to connect a database Microsoft 2000 trough Coldfusion MX to DreamWeaver MX and its doesn’t connect. Here is the message I get:

Connection verification failed for data source: ClearWebCF
[]java.sql.SQLException: [Macromedia][SQLServer JDBC Driver][SQLServer]Login failed for user 'sa'.

The root cause was that: java.sql.SQLException: [Macromedia][SQLServer JDBC Driver][SQLServer]Login failed for user 'sa'.

Thank you in advance

Ps. I am very new at using those tools.
