ADO DB Connection (SQL Server) via ASP.Net web app - help!!!!

dotnet general:

I'm attempting to connect to a SQL Server DB, using ADO, from my new ASP.NET
web application. I can use the same connect string from within a VB.Net app
(windows app) just fine, but I cannot do it from within my web app... Here
is the error I am receiving:

Login failed for user '(null)'. Reason: Not associated with a trusted SQL
Server connection.

I am using windows authentication, which works just fine within my windows
app - I'm using the web server on my local machine... Here is my connect
string and code associated with this:

sDatabaseType = "SQL Server"
sServerName = "MyServer"
sDatabaseName = "MyDatabase"sConnectString = "DRIVER={SQL
Server};SERVER=" & sServerName & ";Trusted_connection=yes;DATABASE=" &
sDatabaseName & ";"
gdcDataConnection = New ADODB.Connection
gdcDataConnection.Open(sConnectString)

I would appreciate any help that you can provide!!!!!

Use the System.Data.SqlClient.SqlConnection -- It is a strong-typed connection to an Sql Server instance. In the .NET world, you no
longer need the ADODB com object as you did with ASP. As a matter of fact, it is recommended to use the SqlClient namespace for use
with Sql Server instead of a generic ODBC (or OLE DB) connection.

// Create a connection object
System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlConnection();

// Connect to the server using windows authentication.
conn.ConnectionString = "Data Source=localhost; Initial Catalog=Northwind; Trusted_Connection=true;";

try
{
conn.Open();

// Todo: Use the connection...
/*
* Check out the other classes in the System.Data.SqlClient Namespace, such as:
* SqlDataAdapter
* SqlDataReader
* SqlCommand
* SqlException
/*
}
finally
{
conn.Close();
}
