Oh, the games people play now. Every night and every day now. Never meaning what they say now. Never saying what they mean. And they wile away the hours. In their ivory towers. Till they're covered up with flowers.
ZoneCheck performs several tests on your DNS zone to ensure that it is correctly configured, and can be safely delegated. The Zone name must be either a Domain name, in-addr.arpa zone, or ip6.arpa zone name.
When a DNS server running on Windows Server 2008 receives a query for a single-label host name, it attempts to resolve the name by first checking for the name in the GNZ. If it is not able to resolve the name by using the GNZ, , it then looks in local zone resource records.NZ is intended to aid the retirement of WINS. It is not a replacement for WINS. GNZ is not intended to support the single-label name resolution of records that are registered dynamically and therefore not managed by IT administrators.
