Hi Muppuri, One of the new features introduced in the Windows Server 2003-based implementation of DNS are stub zones. Its main purpose is to provide name resolution in domains, for which a local DNS server is not authoritative. The stub zone contains only a few records: - Start of Authority (SOA) record pointing to a remote DNS server that is considered to be the best source of information about the target DNS domain, - one or more Name Server (NS) records (including the entry associated with the SOA record), which are authoritative for the DNS domain represented by the stub zone, - corresponding A records for each of the NS entries (providing IP addresses of the servers). While you can also provide name resolution for a remote domain by either creating a secondary zone (which was a common approach in Windows Server 2000 DNS implementation) or delegation (when dealing with a contiguous namespace), such approach forces periodic zone transfers, which are not needed when stub zones are used. Necessity to traverse network in order to obtain individual records hosted on the remote Name Servers is mitigated to some extent by caching process, which keeps them on the local server for the duration of their Time-to-Live (TTL) parameter. In addition, records residing in a stub zone are periodically validated and refreshed in order to avoid lame delegations.
