Hi till now i am used window application in which there is no problem in connection using following code

Dim cnn As SqlConnection
        cnn = New SqlConnection("data source=RAKESH-676DD0E1;initial catalog=rw;integrated security=SSPI")
        cnn.Open()
        Dim da As SqlDataAdapter
        Dim dt As New DataTable
        da = New SqlDataAdapter("select * from publicity", cnn)
        da.Fill(dt)
        DataGrid1.DataSource = dt
        cnn.Close()

As i am not using userid & password instead i am using window authentication

But now i develop web application & used this code & also tried .NET toolbox oledbdataadpter & dataset but when I debug my application then the connection will be failed & show message

please help.......

I'm sure you using SQL Server 2000
So, the error is you didn't give some permission to ASP.NET user who trying access SQL instance, therefore it blocked.
From server security in SQL Server Enterprise Manager, logins right click and add ASPNET user with windows authentication type.
Try running the application again then tell me what happened.
