I have one main network with 3DC's and another remote site with one DC (all part of the one AD). I have recently merged with another company and have a trust in place. They will be accessing resources off my network. When they logon and authenticate on my network for some reason they are being sent to the remote site DC as oppose to the main network DC's. I understand sites and services is the place to go (I think?) I have never set up this before but from my recollection I specify the IP ranges to be associated with the specific servers?
