ConnectionString connected databases

I use Win Untimate 7 and SQL server 2008 Standard.
I want to use Dreamweaver 8 to connect to the database in SQL but when imported connectionString error message: "[Microsoft] [ODBC Driver Manager] Data source name not found and no default driver Specified."
I use both Windows Authentication Mode 2 and SQL Server Authentication.
How you can help your connectionString.
Thank you!

Are you using a system DSN or just the connection string?
Please provide the connection string.
If youre using DSN make sure you setup as a system DSN and not a user or file DSN.

I use connectionstring:
Data Source=Home-PC;Initial Catalog=PWD;User Id=sa;Password=240809966;
