I get "HTTP error 404.3 - Not Found" when i click any of the FEP baselines

Hi Guys,
 
I have an issue with FEP 2010, whenever i try to access any of the Configuration baselines "in the FEP console", i receive an error message (HTTP error 404.3 - Not Found -- The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map).
 
Here is a brief about the my environment; i have the SCCM database deployed on 1 server, SCCM and FEP are deployed on 1 server, the SCCM reporting service point is deployed on the DB server, and the reporting point is deployed on the SCCM server.
 
During the SCCM implementation, i faced an issue with the management point, so i removed it, uninstalled the IIS, installed IIS again and did all the required configuration, then installed the management point, and fortunately i got the SCCM working.

Finally, in order for the clients to report to the FEP server, i had to enable the Desired Configuration Management agent, and deploy on the clients' collection one of the default DCM template that basically are installed with FEP.

I'd appreciate any help!
 
Cheers,
