Here is a bit of info on my setup. We are running windows 2000 server with 2000 AD we have 3 domains(Domain1, 2, 3), each with there own DC, DNS server. There is a trust between the domains with Domain1 being the main one. We recently replaced dc1 on domain1 by dcpromo the old one and dc promo the new one and then installed DNS on it. What I notice now is that when I browse through microsoft windows network through network neighborhood on domain1, i can see domain2 but domain3 does not show up. i am able to ping, nslookup and remote into all machines on domain3, just not able to see it through microsoft windows network. Just wondering if anyone has any ideas.
