        Try changing the Data Source to Data Source=.\\SQLEXPRESS (Assuming you're using the default instance.) You can also check out connectionstrings.com[^] Hope this helps =)

            When connecting to a database with Integrated Security set to true, I don't think you need to specify User ID and Password. :)
