What is your current connection string?

You should be doiong something like..

Server=myServerAddress;Database=myDataBase;Trusted_Connection=True;

or

Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=SSPI;

these came from http://www.connectionstrings.com/sql-server-2005
