What is the process of replicating DNS information from one DNS server to another?
Zone Transfer
What can one do to resolve a dns?
One looking to resolve their DNS issues should enable reverse look-ups on their DNS server. Next, one should check for duplicate records on their DNS server. Finally, one should compare the records on their DNS server and make the necessary changes.
Where can one find more information on a secondary DNS server?
On a computer running a Windows operating system, you can find your DNS Server Address by clicking Start> Settings> Network connections. Then double click on Local Area Connection. Now click the properties button and select Internet protocol. Click on properties and find Preferred DNS Server.
Integration between DHCP and DNS?
Traditionally, DNS and DHCP servers have been configured and managed one at a time. Similarly, changing authorization rights for a particular user on a group of devices has meant visiting each one and making configuration changes. DHCP integration with DNS allows the aggregation of these tasks across devices, enabling a company's network services to scale in step with the growth of network users, devices, and policies, while reducing administrative operations and costs.This integration provides practical operational efficiencies that lower total cost of ownership. Creating a DHCP network automatically creates an associated DNS zone, for example, reducing the number of tasks required of network administrators. And integration of DNS and DHCP in the same database instance provides unmatched consistency between service and management views of IP address-centric network services data.Windows Server 2003 DNS supports DHCP by means of the dynamic update of DNS zones. By integrating DHCP and DNS in a DNS deployment, you can provide your network resources with dynamic addressing information stored in DNS. To enable this integration, you can use the Windows Server 2003 DHCP service.The dynamic update standard, specified in RFC 2136: Dynamic Updates in the Domain Name System (DNS UPDATE), automatically updates DNS records. Both Windows Server 2003 and Windows 2000 support dynamic update, and both clients and DHCP servers can send dynamic updates when their IP addresses change.Dynamic update enables a DHCP server to register address (A) and pointer (PTR) resource records on behalf of a DHCP client by using DHCP Client FQDN option 81. Option 81 enables the DHCP client to provide its FQDN to the DHCP server. The DHCP client also provides instructions to the DHCP server describing how to process DNS dynamic updates on behalf of the DHCP client.The DHCP server can dynamically update DNS A and PTR records on behalf of DHCP clients that are not capable of sending option 81 to the DHCP server. You can also configure the DHCP server to discard client A and PTR records when the DHCP client lease is deleted. This reduces the time needed to manage these records manually and provides support for DHCP clients that cannot perform dynamic updates. In addition, dynamic update simplifies the setup of Active Directory by enabling domain controllers to dynamically register SRV resource records.If the DHCP server is configured to perform DNS dynamic updates, it performs one of the following actions:The DHCP server updates resource records at the request of the client. The client requests the DHCP server to update the DNS PTR record on behalf of the client, and the client registers A.The DHCP server updates DNS A and PTR records regardless of whether the client requests this action or not.By itself, dynamic update is not secure because any client can modify DNS records. To secure dynamic updates, you can use the secure dynamic update feature provided in Windows Server 2003. To delete outdated records, you can use the DNS server aging and scavenging feature.
What are the difference between peer to peer networks ans client server?
Peer to Peer networking has no central "hub" to store the data to be downloaded. When a Client needs information, they connect to other clients on a network to download that information. An example of Peer-to-Peer networking is BitTorrent. Client-Server Networks use a central computer as a hub to store information. So when a client needs to access information, they need to access the Server for that data. An example of a Client-Server Network is any website.

Where can one learn what is a DNS server?
The network operating system that one is working with will determine the specific information an individual searches for when looking for information on a DNS (Domain Name Service) server. One can learn from books at their local book store or library about DNS on Windows and Linux NOS's, or one could go to their local community college and take a basic Networking class to learn what a DNS server is.
How can I speed up my Internet browsing by changing DNS settings?
One can increase the speed of internet browsing by changing their DNS server address. A list of DNS servers can be found on the Comcast website. Changing the DNS address to a more reliable one should increase the browsing speed of the computer.

What do the DNS servers do with the information learned from the iterative queries?
An iterative name query is one in which a DNS client allows the DNS server to return the best answer it can give based on its cache or zone data. If the queried DNS server does not have an exact match for the queried name, the best possible information it can return is a referral (that is, a pointer to a DNS server authoritative for a lower level of the domain namespace). The DNS client can then query the DNS server for which it obtained a referral. It continues this process until it locates a DNS server that is authoritative for the queried name, or until an error or time-out condition is met.This process is sometimes referred to as "walking the tree," and this type of query is typically initiated by a DNS server that attempts to resolve a recursive name query for a DNS client.
What is the process by which one DNS server sends a name resolution request to another DNS server?
referral
What are the types of DNS zones in windows server 2003?
Primary zoneWhen a zone that this DNS server hosts is a primary zone, the DNS server is the primary source for information about this zone, and it stores the master copy of zone data in a local file or in AD DS. When the zone is stored in a file, by default the primary zone file is named zone_name.dns and it is located in the %windir%\System32\Dns folder on the server.Secondary zoneWhen a zone that this DNS server hosts is a secondary zone, this DNS server is a secondary source for information about this zone. The zone at this server must be obtained from another remote DNS server computer that also hosts the zone. This DNS server must have network access to the remote DNS server that supplies this server with updated information about the zone. Because a secondary zone is merely a copy of a primary zone that is hosted on another server, it cannot be stored in AD DS.Stub zoneWhen a zone that this DNS server hosts is a stub zone, this DNS server is a source only for information about the authoritative name servers for this zone. The zone at this server must be obtained from another DNS server that hosts the zone. This DNS server must have network access to the remote DNS server to copy the authoritative name server information about the zone.You can use stub zones to:Keep delegated zone information current. By updating a stub zone for one of its child zones regularly, the DNS server that hosts both the parent zone and the stub zone will maintain a current list of authoritative DNS servers for the child zone.Improve name resolution. Stub zones enable a DNS server to perform recursion using the stub zone's list of name servers, without having to query the Internet or an internal root server for the DNS namespace.Simplify DNS administration. By using stub zones throughout your DNS infrastructure, you can distribute a list of the authoritative DNS servers for a zone without using secondary zones. However, stub zones do not serve the same purpose as secondary zones, and they are not an alternative for enhancing redundancy and load sharing.There are two lists of DNS servers involved in the loading and maintenance of a stub zone:The list of master servers from which the DNS server loads and updates a stub zone. A master server may be a primary or secondary DNS server for the zone. In both cases, it will have a complete list of the DNS servers for the zone.The list of the authoritative DNS servers for a zone. This list is contained in the stub zone using name server (NS) resource records.When a DNS server loads a stub zone, such as abc.xyz.com, it queries the master servers, which can be in different locations, for the necessary resource records of the authoritative servers for the zone abc.xyz.com. The list of master servers may contain a single server or multiple servers, and it can be changed anytime.

Every time you ask for how to find your primary and secondary dns the answer is always something about going to your DNS server hows that your primary and secondary DNS if its only one set of numbers?
It means, you do not have secondary DNS server.
A DNS Server can be primary for one zone and secondary for another True or False?
False. The DNS records cannot be added directly to the secondary DNS zone. The secondary DNS zone can receive the updated records only from the primary DNS zone of the DNS server.
Can some one give me the fastest dns server numbers?
preferred dns: 68.87.64.146 alternate dns: 208.67.222.222 or 208.67.220.220
How can one determine a primary DNS?
A DNS can be determined by opening the command prompt on the start menu, type "cmd" and press enter in the black window, type in "ipconfig/all", scroll down the information displayed until DNS server is visible, the first address is the primary DNS. DNS stands for Domain Name Server Commands should be typed without the quotation marks.
