Reporting Server error

When I log onto the homepage of my reporting server I get a big RED "X" in the upper left hand corner with the word "Error". There is nothig in the event viewer to indicate a problem. I have looked at the IIS permissions and they all appear to be set properly.

Are you trying to connect to <servername>/Reports or <servername>/ReportServer?

What version are you using?

Have you checked the RS logs in ...\Program Files\...?
