<script runat="server">

Sub Page_Load(sender As Object, e As EventArgs)

Dim myConnectionString As String = "Server=IP Address of DB Server;Database=DB Name;User ID=uname;Password=pwd;Integrated Security=SSPI"
Dim myConnection As New SqlConnection(myConnectionString)
Dim cmdTest As SqlCommand
Dim rdrTest As SqlDataReader
myConnection.Open()

cmdTest = New SqlCommand ("select * from tblAdmin")
rdrTest = cmdTest.ExecuteReader

gridTest.DataSource = rdrTest
gridTest.DataBind
rdrTest.Close

You can't have IIS and the SQL DB on different machines and use Integrated Security.

Accessing SQL Server from a Web Application

Use Windows integrated security. This option passes the user's credentials to SQL Server. Because of delegation issues, this is practical primarily if SQL Server is on the same computer as IIS and your users must be on the same domain as the Web server computer.
