RS2005 on Win2000

I've followed a couple of threads on this, but still haven't quite resolved the issue. RS 2005 is installed on a Win 2000 Server. The service seems to be running perfectly, but when I navigate to <localhost>\ReportServer, I get:

Reporting Services Error
--
The report server has encountered a configuration error. See the report server log files for more information. (rsServerConfigurationError)
Access to the path 'D:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer\RSReportServer.config' is denied.

I've manually configured the webserviceaccount to the default aspnet machine logon since it's greyed out in the rs configuration screen. Once I manually added that logon, I've not had any errors or warnings in my log files. I've also tried messing with the folder permissions for this path, but no luck. So, I've read and tried a lot of things suggested on this forum. Anyone have the magic wand out there?

Thanks

OK, problem solved. The ASPNET machine logon permissions weren't propogating down the full folder structure for some reason. It works now.
