I’ve got a forest with 11 domains. Each domain represents a seperate company which conencts to our head office network. Most of the domains are 1st level (below the root) and contain at least one DC on site with DNS & WINS & DHCP.
I am normally accustomed to setting each of the remote domains as seperate sites and letting Sites & Services create automatic links b/w each site for replication. I was a little shocked when I saw the S&S setup here. It looks like this:
Active Directory Sites & Services [ntserver.v.com.au]
