We have run a 4500 core switch for about a year in one of our buildings. It is part of a larger active directory network. None of the computers in the building will show up in network neighborhood. They will show up inside the building though. Our dns is run by our parent forest organization and even their DC will not show up outside the building.
This is an issue as many programs use that to do their work. Trying to add by ip address which does work is a pain.
Any help would be appreciated.
