Error Starting Reporting Services Report Manager Beta2 - ASP.NET I

[Mark]

I believe this is an ASP.Net 2 framework problem because the ASP Admin
Service fails to start with the message - "Error 2 - The system cannot find
the file specified"

I get the following error trying to start Report Manager after installing
SQL2005 beta December CTP. I installed side-by-side with a full SQL2000
implementation on Windows 2003 Server:

Server Error in '/Reports$SQL2005' Application.
