Can't Find Server Name when Starting Nslookup.exe
When starting the Nslookup.exe utility, the following error may occur:
*** Can't find server name for address w.x.y.z: Non-existent domain
This error occurs when there is no PTR record for the name server's IP address. When Nslookup.exe starts, it does a reverse lookup to get the name of the default server. If no PTR data exists, this error message is returned. To correct make sure that a reverse lookup zone exists and contains PTR records for the name servers.

Nslookup on Child Domain Fails
When querying or doing a zone transfer on a child domain, Nslookup may return the following errors:
*** ns.domain.com can't find child.domain.com.: Non-existent domain
*** Can't list domain child.domain.com.: Non-existent domain
In DNS Manager, a new domain can be added under the primary zone, thus creating a child domain. Creating a child domain this way does not create a separate db file for the domain, thus querying that domain or running a zone transfer on it will produce the above errors. Running a zone transfer on the parent domain will list data for both the parent and child domains. To work around this problem, create a new primary zone on the DNS server for the child domain.
