Hi All, It's my first question, so thanks a lot in advance. I have currently pre deployed Primary site S01 in Forest A and Primary Child Site S02 in Forest B. There is no trust between them. 1. Used Preinst tool to exchange the keys 2. Used a Standard Sender 3. Configured the Destination Server (S01 and S02) and Site Address (domainA\sccmadmin) and (Domain B\sccmadmin). Am i missing something as the Parent child relationship is not working, no padlocks on child collections and no new site in the primary site console.

See sender.log on both sites and check if the sites can communicate with each other.

See sender.log on both sites and check if the sites can communicate with each other. By lookingat the sender logs I was able to see that the resolving of FQDN on both sides was not setup correctly. Thanks.
