I need to set up a trust relationship between our Germany office and NewJersey office. The offices are connected with a VPN tunnel and each office has their own separate domain each in it's own forest. Do the domains need to be in the same forest in order for a trust relationship to be established? And if so, how do i merge the domains into the same forest? I basically need to set it up so that the New Jersey domain trusts the Germany domain. What steps need to be taken to actually set up the trust relationship?

Yes you can create a trust between domains in disparate forests. Make sure that WINS, DNS, or the LMHOSTS file is configured correctly to locate the DC's, and that TCP/IP is configured correctly on all of the domain controllers that are involved.

In Server 2003, you can have cross-forest trusts. Regarding the LMHOSTS solution, as poster 1 said, that's news to me, but try it, it might work.

I tried adding an entry to lmhosts using #PRE and #DOM and that did not work either. Is there a limit as to how many characters the domain name can be? our domain name is 17 characters long. could that be the problem?

I set up DNS zone files on both sides so that now i can ping each domain controller from the other domain by host name. i have also found KB article 312003 and have followed all of the suggestions in the article since the error in the article is the same error i get when i try to actually set up the trust.
