SCCM Untrusted Forest Issues Require the Site server to Initiate Connection
If you think about an untrusted forest scenario, there is “no way” the remote site system can contact your site server (by default).
Whereas the site server can initiate the connection with the remote site system using “site system installation account.”
Navigate – \Administration\Overview\Site Configuration\Servers and Site System Roles. Right-Click on the Site System role.
Select the properties. Click on General Tab. Enable Require the site server to initiate connections to this system option.
Click on Use another account for installing this site system. Enter User name and password of remote servers local admin.
Once you select the “site server to initiate connection” option for a remote site system, the site server initiates a connection, and it will copy all the required files to respective folders on the site server.
