Try chaning the user that runs the Application Pool, it seems that you are trying to access some COM objects that your IIS_USR don't have access too.

You can also try using Impersonation.

Do you use a third party dll like Crystal Reports that may not be installed correctly or at the correct version? It could be that said third party dll is trying to access the windows or .net temp folders or a related dll that does not exist.

There is an security issue with COM libraries with Windows Server2008 R2. This security issue prevent to use COM libaries with Server 2008 R2. If the server was 2003 version, it coul be work.
