Modifications necessary to dns for accommodating rodc
What is the purpose if the Global Names Zone in Windows Server 2008 DNS servers?Global Names Zone is intended to aid the retirement of Windows Internet Name Service.A domain-integrated zone on a RODC will not accept Dynamic updates.A file-backed DNS zone on such a RODC would be able to accept dynamic updates, as it has a separate database from the domain database. The DNS sever in windows server 2008 makes data retrieval faster by executing background zone loading.In addition to the zone corresponding to the AD domain that RODC is part of, DNS should be hosting Domain DNSZones and Forest DNSZones application partitions (which you can configure using dnscmd command line utility).An ordinary Domain Controller can do nifty things, like add a new user/group, make mods to it's own system to accommodate updates, ect.After enabling the Global Names Zone, the administrator must manually create, add, edit and delete name records from that zone. How is this different from the way DNS handles ordinary domain controllers?All of the modifications required for accommodating a Read Only Domain Controller are handled through the “adprep / rodcprep step, which modifies the domain schema.

Server 2008 allows a Domain Controller to not contain a DNS server. In the past, enterprises with zones containing large numbers of records in active directory experienced delays of up to an hour or more when the DNS server services in windows 2003 tried to retrieve the data from active directory on restart. How does background zone loading promotes efficiency in the name resolution?
