Logon Problem - I am an idiot "ID 10 T"

Tried using webmatrix code builder to simply bind a web grid to a sql table.
Works great in WEbMatrix, but when I move the code to Visual Studio.VB,
I get a logon error when the code is run.

Any Help is Greatly Appreciated... I am stuck....

Here is the code:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

DataGrid1.DataSource = GetCustomers()
DataGrid1.DataBind()

End Sub

Private Function GetCustomers() As System.Data.SqlClient.SqlDataReader

Dim connectionString As String = "server='localhost'; trusted_connection=true; Database='ASPExamples'"
Dim sqlConnection As System.Data.SqlClient.SqlConnection = New System.Data.SqlClient.SqlConnection(connectionString)

Dim queryString As String = "SELECT [Customers].* FROM [Customers]"
Dim sqlCommand As System.Data.SqlClient.SqlCommand = New System.Data.SqlClient.SqlCommand(queryString, sqlConnection)

sqlConnection.Open()
Dim dataReader As System.Data.SqlClient.SqlDataReader = sqlCommand.ExecuteReader(System.Data.CommandBehavior.CloseConnection)

Return dataReader

End Function

End ClassProblem is solved,

It was SQL Server Security, I had to add a user <Machine Name\ASPNET>
..and explicitly give permissions for SELECT, UPDATE, Etc...

Funny, but the same exact code in WEB MATRIX did not require this to be done.

Any insight on this please respond....
