Ax2009 Instalation error

[ist]

Hi,
I try ito nstall Dynamics Ax 2009 and I follow instruction in AxInstallationGuide. All is OK till the moment when I install prerequisites for Enterprice portal, Role Center and Workflow (WSS - Windows SharePoint Services) . The problem is that Reporting Services stop work, and when I try to install Reporting Extension, setup wizzard show error message that says "Reporting server was not configured properly". In setup log file I found an error 404 - Web page not found. I read that when WSS is installed, the Default web page in IIS is stopped and AxInstallationGuide recomended us to change port. I change port on Default Web Site, start it and restart IIS. I made this but I can't install Reporting extension. Before I install WSS I can start properly SQL Reporting servces and Reporting services was correctly configured.
