I have a windows 2000 domain with about 22 machines and 25 licenses. Strange thing has happen. Up until recently all machines logged into the domain were visible to all computers on the domain, but now one is hidden, still connected, but hidden. I can type its network address in (ie \\machine) and browse all of it's shared folders but I can't browse to it through windows network browser. It has been visible for the past six months then all of a sudden today I can't find it with out typing in its address. Is this a DNS problem?
