Answer 1

DNS = Domain Name Server

To know more information click on the following link

http://en.wikipedia.org/wiki/Domain_name_system#History_of_the_DNS


The domain name space consists of a tree of domain names. Each node or leaf in the tree has one or more resource records, which hold information associated with the domain name. The tree sub-divides into zones. A zone consists of a collection of connected nodes authoritatively served by an authoritative DNS nameserver. (Note that a single nameserver can host several zones.)

When a system administrator wants to let another administrator control a part of the domain name space within his or her zone of authority, he or she can delegate control to the other administrator. This splits a part of the old zone off into a new zone, which comes under the authority of the second administrator's nameservers. The old zone becomes no longer authoritative for what comes under the authority of the new zone.

A resolver looks up the information associated with nodes. A resolver knows how to communicate with name servers by sending DNS requests, and heeding DNS responses. Resolving usually entails iterating through several name servers to find the needed information.

Some resolvers function simplistically and can only communicate with a single name server. These simple resolvers rely on a recursing name server to perform the work of finding information for them.


I hope u understood this one...

DNS is Domain Naming System, a system used to covert names into IP addresses. To configure DNS, you need to install the DNS Server Service first.

To configure Active Directory, you need to first install Active Directory by configuring a stand alone machine to be a Server.

On the Internet, the Domain Name System (DNS) stores and associates many types of information with domain names; most importantly, it serves as the phone book for the internet, translating human-friendly domain names and computer hostnames, e.g. en.wikipedia.org, into computer-friendly IP addresses. It also lists mail exchange servers accepting e-mail for each domain. In providing a worldwide keyword-based redirection service, DNS is an essential component of contemporary Internet use.

Answer 6

DNS - Domain Name Systems.

At the time of installing Active Directory, u must have to install DNS or configure it on domain controller. It is not necessary to install DNS in which server u have installed Active Directory.

Any Problem call me.

Answer 7

when installing active directory u can intergrate the DNS server with it. thats is the best and easy way to use.

coz it will automatically add up all the host entires in the DNS server, which will help in searching the network resources.

Answer 8

Think of it this way; if you want to call Sam Brown the phone set doesn't understand Sam Brown, it only understands numbers, same thing for the Websites or any network device, it only undestands IP addresses. so if I wanna go to www.yahoo.com I need to know the corresponding IP address, to do this Network Gurus invented the DNS, Domain Namer service, which will translate the www.yahoo.com to a certain IP address..

Hope this helps..
