Thank you, Steven, I will definitely look over the article you referred to. But one thing I didn't make clear yesterday when I posted the question, is the reports aren't run from the server the SQL Server is on. i.e.: they're not run from Report Manager. Instead the reports are .RDLC files within the ASP.NET application, so technically they're running "locally", within the ASP.NET app. I don't know if that will make any difference or not.
