Report manager HTTP status 400: Bad Request

I am having trouble to access Report Manager on a fresh SQL Reporting Services install on Win 2003, SQL 2000 SP3a machine. /ReportServer works fine, I've created a Virtual Directory /OnlineReports to allow anomynous access but /Reports doesn't work. So I can't add IUSR to the folder I need anomymous access on. Can somebody please help?

Thanks in advance.

Is Report Manager configured correctly? Can you look in RSWebApplication.config and see what ReportServerUrl is set to?

Yes, here's what it shows <ReportServerUrl>http://www.domain.com/ReportServer</ReportServerUrl>

www.domain.com/ReportServer works but www.domain.com/Reports doesn't.

Thank you.

Well, now I have a different error. It said The request failed with HTTP status 401: Unauthorized when I go to www.domain.com/Reports. I log in as Administrator and it still said I am unauthorized. Do I have to uninstall and reinstall to get this working?

Thank you.

Add a DWORD entry called DisableLoopbackCheck to
HKLM\System\CurrentControlSet\Control\Lsa. Setting this key to a value of 1 fixed the issue.
