Understanding Zone Types
Applies To: Windows Server 2008, Windows Server 2008 R2
The DNS Server service provides for three types of zones:

Primary zone
When 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 zone
When 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 zone
When 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

    Now let’s move on to the second, much larger branch supporting around thirty users and or workstations. You stated that this branch has much better network connectivity than its smaller counterpart. In this case, I would recommend a DNS server set up in the primary zone. The primary zone is the primary source of information. I would also further suggest moving your servers from the smaller branch to the larger branch. All files from the smaller branch could be accessed via a Virtual Private Network (VPN) remote link. This would allow the smaller branch the ability to use a much smaller and less expensive router, which might help with the lag the users have experienced.…

    Review of the Hot Zone

    Richard Preston weaves a true tale about a chilling story of an Ebola virus (A disease-causing agent smaller than a bacterium, consisting of a shell made of proteins and membranes and a core containing DNA or RNA. A virus depends on living cells in order to replicate.) outbreak that occurs in a suburban Washington, D.C. laboratory in 1989. In this laboratory, monkeys being used in scientific experiments quickly sicken and die due to a filovirus (A family of viruses that comprises only Ebola and Marburg.). From this introduction, Preston tells about an explosive chain of lethal transmissions (Sore of biological meltdown wherein a lethal infectious agent spreads explosively through a population, killing a large percentage of the population.), which begins far from this Washington, D.C. laboratory and allows the laboratory to become a hot zone (Area that contains lethal, infectious organisms.). In graphic detail, Preston presents a meltdown of a man's body, Charles Monet, which is invaded by a filovirus in a part of the African rain forests that also presents the world with the HIV (Human immunodeficiency virus, the cause of AIDS. It is an emerging Level 2 agent from the rain forests of Africa. Exact origin unknown. Now amplifying globally its ultimate level of penetration into the human species is completely unknown.) virus through the Kinshasa Highway (AIDS highway. The main route by which HIV traveled during its breakout from the central African rain forest. The road loinks Kinshasa, in Zaire, with East Africa.). This becomes the first known index case (First known case in an outbreak of infectious disease. Sometimes spreads the disease widely.) and allows extreme amplification (Multiplication of a virus everywhere in a host, partly transforming the host into virus.) to occur as the virus spreads its billions of replicated copies triggering a chain of lethal transmissions which could ultimately threaten…

    What exactly is Ebola? A question I asked myself before beginning my assignment. Ebola is a virus disease that is caused by infection with certain virus species. This virus causes various symptoms such as high fevers, headaches, weakness, vomiting, muscle pain, rashes, and redness in the eyes. While reading “Something in the Forest,” I found a couple of sections to be mysterious but that contained clues on to how Charles Monet may have obtained his deadly disease on his trip to Kitum Cave. “Did he run his hands over the stone trees and prick his finger on a crystal?” (Preston, Pg. 35) The moment I read this I became filled with curiosity, did this wound actually occur? If it did, did he cover it or left it out in the open? As a medical assistant, I am aware that if something as simple as dust or dirt touches a wound it can cause…

    A stub works by placing a short circuit across the line at the frequency of interference. Placing a stub on a line forms a voltage divider between the line impedance and the stub impedance. The higher the line impedance at the point of connection, the greater the attenuation. If the line is well matched…

    It’s been five years since the SEZ Act 2005 came into being. Over 580 SEZ approvals, much real estate speculation, half-a-dozen farmers’ protests, and an economic slowdown later, it is time for the Ministry of Commerce to admit that the policy has been a damp squib on the economic front. Developers who were falling over each other to get their SEZ plans approved seem to be looking for greener pastures, as they now line up to get their SEZs denotified or withdrawn. Many others continue to seek extensions to their in-principle approvals, even as they experience problems accessing land or coming up with the requisite finances. In October 2010, the Board of Approvals at the ministry, which was clearing more than 40 projects an hour a few years ago, did not receive a single proposal!…

    The law of the sea provides for a legal framework in terms of the creation of rights and obligation of states at sea, it is a catalyst of cooperation and dialogue, but, may, at time, be the source of tension. It is undisputed that the establishment of the 200 mile EEZ has been one of the most significant changes in the field of international law. High seas that were earlier open to all countries have now, been channelized and allotted to the coastal states. The UNCLOS is a recent document that may even be called a ‘constitution for the oceans’ ; it ensures that there are certain principles that are adhered to and that there is uniformity of practice.…
