Two Windows DNS servers on the same LAN segment.

[George]

I am not a DNS guru and have only just begun using Windows 2000 Server
DNS.  I have also been maintaining the records for our Unix based DNS
server.  I was wondering if it is ok to have two Windows 2000 Server
systems, both running, DNS server services.  They will both have the
exact same Zones, Aliases, Records, etc.  Active Directory is also
running on these systems.  It sounds reasonable to guess that two
Windows Servers could be active, but I just wanted to ask before I
assumed so.  Seems I remember hearing somewhere about primary and
secondary, but was not sure how that fit into the current Windows 2000
environment.  Thanks to all.
