How establish trust relationship between two forest?

Hi all,

       Recently, in order to restore my exchange2000 database, I create a offline server in my network(I createa new forest a new domain for this offline server). I can't attach my tape backup locally to the offline server so I need to do it using remote agent and backup exec. So my problem is how to establish the trust relationship between these two forest so my production server can allocate the offline sever?
