I'm new to Visual Studio.NET and Visual Basic.NET. While trying to run the
sample application, it shows an error message as shown below. I have an SQL
Server containing the sample database Northwind used in this application.
Authentication mode set in Web.config is Windows; Mixed mode in the SQL
Server. Any idea how I can resolve this problem? Thanks...

Check the user name and password. Make sure SQL Server is running in mixed
mode. Also, make sure you have the right server name.

What version of SQL Server? With 6.5, you will want to look at this:

Thank you Cowboy for your reply

I'm using SQL Server 2000, Visual Studio.NET 2003. The SQL Server is set to mixed mode

When you say 'must have the right Server name', my SQL server name is "NB", do I have to reference it in my main.aspx? My sqlconnection string in the main.aspx is as follows

protected const string SQL_CONNECTION_STRING =
"Server=localhost;" +
"DataBase=northwind;" +
"Integrated Security=SSPI"
