Problem displaying a report in a web page?

Question:

I have Windows authentication for my Reporting Services and when I create a report for web [VS 2008 and Report Viewer Control] using back end data on my SQL Server RC0 and try displaying it, I get an error - the web page is not displayed?

Possible answer:

You need to make sure whether you have established a RC0 login for ASPNET which is usually \ASPNET. If it is not present then you can add it from the SQL Server Management Studio.
