Nearly resolved my domain trusting issue, HELP

Hello All,

I was having problems with setting up a trust between my office and a remote office, i set the trust up but when i go to validate the trust it says cannot create both sides of the trust because a primany domain controller cannot be found.

I have been working on the hole trust problem for 3 days now, had to rewrite DNS, add forwarders, add lmhost and host files i hope someone can help with this so i can put it to rest
