SQL Connection string for Windows CE7

I am trying to connect a Skorpio X4 to our local SQL Server database with little success.
I am using the below connection string in my application. This works fine on other devices running Windows CE6. Since the Skorpio is running Windows CE7, is there a difference?

Data Source=192.168.XXX.XXX\SQLEXPRESS;Initial Catalog=databasename;Integrated Security=SSPI;User Id=username;Password=password
