Hello,
Regarding the SMS_Site_componant_manager event ID4909. If you go to Administration | Hierarchy Configuration | Active Directory Forests, you see the correct forest right? And if you check the properties of that forest, are you publishing with a specific account or with the default machines account? If you are publishing with a specific account, you need to give that account rights to the System Management container.
Also disable any antivirus you have running on all of your site servers, then restart the SMS Site Component Manager service on your primary site server.
Hope this helps with your query!
