Can't open reports with Intranet user

Hi,
I made some reports and I deployed them on my local report server. I want
someone in the Intranet to be able to view them. I did set up the role to
make the intranet group to be able to browse my reports. They can view the
list of the report when they access it from http://server/ReportServer But
they just can't view it when they click on a report. It says they don't have
permissions to open ReportViewer.aspx.
I wonder why it is the problem.Ok I found the problem. The file ReportViewer.aspx didn't gave the
authorization to my Intranet group.
