I have seen some information about setting up entries as your
suggested but perhaps I'm missing something. Here is the part that
confuses me; Windows 2000 DNS does not allow '.' in the host names (at
least from the console) so the only way to enter in this format is to
create a new zone for each host and name the zone as you suggested.
If that is in fact true, once the zone is created what entries do I
need under that zone? Don't I need some sort of host record?
