This means that your SQL Server´s Authentication mode is set to Windows
only. You can do two things:
1. Set the authentication to mixed mode (Windows and SQL Server)
2. Instead of providing a user and password, use your domain user
credentials by adding "Integrated Security=True" to your
Connection string.
That should do it,
