Domain trusts…

Ok, this a simple one….

I have 2 w2k servers, both are differnt domains in completely seperate forests. I need to run the microsoft active directory migration tool. To do this a trust be set…. I a DNS host file on each server’s AD, but they still won’t talk. I assume they need to be comunicating before I can create the trust….

Any thoughts…. What am I missing? Something in DNS or cofiguring the trust itself.

I get the following error “Can’t locate RPC server”…

Thanks
