Hi WIN2003 SP2 machine has an uptime robot installed, to check 200 DHCP machines in LAN, every 3 minutes, if they are online. It checks over the host names and not over IP addresses. This costs a lot of traffic on internal AD DNS servers, so I would like to install DNS service on this machine locally. My problem is to choose appropriate DNS zone: stub, secondary, forwarding etc.? Thanks in advance for any help - much appreciated!
