Either the password you provided is not valid or the user is disabled. I also have to ask, why are you using the sa account? Best practice is to disable that account. I would create a user for your needs granting the least permissions needed to complete your tasking.

Creating a user can be done with this code. Windows Login: CREATE LOGIN [domain\user_name] FROM WINDOWS; GO SQL Login: CREATE LOGIN new_userName WITH PASSWORD = 'password'; GO You should review this page as well. http://msdn.microsoft.com/en-us/library/aa337562.aspx
