prompted for username & password when opening a report

Hello,

I was wondering if anyone could help me with the issue I am having.  I am using a Winform application using Crystal Report Viewer for VS2010.  When I execute the report, I get prompted for the username and password every time.

I am running it on a Windows 7, SQL Server 2005 Express, .NET 4.0.  I didn't have this issue when I was running it on Windows XP, SQL Server 2000, .NET 2.0.

Any help would be appreciated...

Thanks,

Bryan
