Hey all I'm attempting to connect with my SQL Server which i log into using my home windows authentication user title and password. However, after i use that information within the code below it informs me that it may not connect...

    Dim connetionString As String
    Dim cnn As SqlConnection
    connetionString = "Data Source=MSSQLPROD;Initial Catalog=MS435_PROD;User ID=me.here;Password=mypassword;"
    cnn = New SqlConnection(connetionString)

    Try
        cnn.Open()
        MsgBox("Connection Open ! ")
        cnn.Close()
    Catch ex As Exception
        MsgBox("Can not open connection ! ")
    End Try

You're using SQL Server authentication whenever you specify a person title and password within the connection string. Take away the user title and password and can include:

Data Source=MSSQLPROD;Initial Catalog=MS435_PROD;Integrated Security=SSPI

Which will make the link with make use of the Home windows authentication from the context performing the code.
