Firewall Wizards: safety of unidirectional NT trusts

[hermit921 <hermit921 () yahoo com>]

I have been tasked with permitting M$ networking access between an NT 
server on the DMZ an other Windows machines behind the firewall.  My plan 
is to not let the DMZ machine initiate any connections to the internal 
machines, but they can initiate connections to the DMZ machine.  The DMZ 
machine should be set up to trust the internal machine, but the internal 
machine should not trust the DMZ machine; I know I can't control this on 
the firewall.  I don't know much about M$ networking, I don't get to make 
decisions, I just implement firewall rules whether I like them or not.
My main question is:  is this unidirectional connection initiation and 
trust help much more secure than bidirectional?  Given that I have to allow 
this network traffic, can I do any better on the firewall rules?
