i will be setting up a 2 way domain trust this weekend between 2 domains
one domain has 2 sites, and 4 domain controllers (call this domain1)
the other domain has 6 sites and about 8-10 domain controllers (call this domain2) each of the DCs are paired up, and on different networks (i.e. 2 are on 10.1.1.x, 2 are on 10.1.2.x, etc)
there are firewalls between all of the sites
so my question is- what ports need to be opened, and what servers would i need to open these ports for?
do i need to open all the ports to all the domain controllers to/from domain1 and domain2? or can i just open ports to/from 2 of the domain controllers in domain2, to domain1?
im sure this is confusing
