I am unable to install Reporting Services on our new Windows 2003
Server.

I have tried several times.

I have given ASPNET administration privileges.
I have tried the install via remote desktop and VNC.
I have tried various systems and local accounts all of which work on
other servers.

After the install I get a warning: Setup could not initialize error,
which said to
manually initialize

When I navigate to
http://localhost/Reports/Pages/Folder.aspx
or http://localhost/Reportserver

I get this error:
An internal error occurred on the report server. See the error log for
more details. (rsInternalError) Get Online Help The system cannot find
the file specified.

I get this warning from the Application Event Log
Event Id: 5603

A provider, ReportingServicesWMI, has been registered in the WMI
namespace, root\Microsoft\SqlServer\ReportingServices\v8, but did not
specify the HostingModel property.  This provider will be run using the
LocalSystem account.  This account is privileged and the provider may
cause a security violation if it does not correctly impersonate user
requests.  Ensure that provider has been reviewed for security behavior
and update the HostingModel property of the provider registration to an
account with the least privileges possible for the required
functionality.
