I made a very simple ASP.NET web page that accesses Microsoft SQL Server 2000 and reads data from the sample database "Northwind", the page works successfully on Windows XP, I use the user ASPNET to connect the web page to the SQL Server.
The problem is that I'm now using Windows Vista Home Premium, when I tried to run the page; I get the error that the user is not authenticated.
Can I get help please in this problem?
Thanks

What authentication method are you using? I would assume Windows Auth from the problem description. Try using SQL Authentication so you can eliminate the OS as a source of the problem.
