One building's netbios names do not show up in the other buildings. We are W2K3 domain with 5 buildings connected by fiber. There are DCs at each buidling. One building can see all the rest of the computers in all buildings but the other 4 buildings cannot see that one building. What else is interesting is that some of the computers are notebooks and when using the wire can see everything but on wireless cannot see its own building.
I have a Cisco 4500 core switch.
