Dear all, I have some questions regarding the trust relationship between two domains. let say my company owns domain A and got computers joined this domain. One day, my company decided to let Domain B users (OTHER COMPANY) to access Domain A's resource, especially it should allow login via Domain A's computer using Domain B' certificate (login ID). So i planed to setup a non transitive one way outgoing external trust relationship from Domain A to B. My question: Is that correct? If the relationship have been set, Can Domain Admin from Domain B, remote desktop to Domain A's domain controller if RDC is enabled? Many thanks Daniel
