I have a new SQL 2005 reporting services installation and it doesn't work.

Database access works fine.

I've setup a new IIS site, set it to run on port 90. It has the two virtual folders - Reports and ReportServer. I can access ReportServer just fine, but Reports (the report manager) throws HTTP 400 error.

I've changed the URL in rsreportserver.config and RSWebApplication.config but it still throws that error.
