NT1330 Mr. Ajero Assignment 1 September 14, 2015 DNS – Domain Name System DNS is a hierarchical representation of all the IT devices and their sub-domains in a (company) network. So, in case you see an address like mail.subdomain.company.com, you can easily recognize the name of the system (mail), name of the sub-domain (sub-domain), name of the company (company) and the name of the primary domain (.com). DHCP – Dynamic Host Control Protocol A DHCP server automatically assigns the IP addresses

Contents What is the purpose of the Global Names Zone in Windows Server 2008 DNS servers? Explain modifications necessary to DNS for accommodating Read Only Domain Controllers (RDOC). How is this different from the way DNS handles ordinary domain controllers? Explain background zone loading? How does background zone loading promote efficiency in name resolution? Explain how DNS has been modified to add support for IPv6. How can DNS distinguish between IPv4 and IPv6 host in determining which

updates IP addresses and DNS records for this computer. If this service is stopped, this computer will not receive dynamic IP addresses and DNS updates. If this service is disabled, any services that explicitly depend on it will fail to start. Dnscache The DNS Client service (dnscache) caches Domain Name System (DNS) names and registers the full computer name for this computer. If the service is stopped, DNS names will continue to be resolved. However, the results of DNS name queries will not be cached

DNS zones are categorized by where information is stored, whether they are able to be written to, and the type of data they send and receive. Zones can be kept in an Active Directory or in text files. Primary Zones- are a zone that hosts a read and writes copy of the DNS zone in which records are produced and administered. Only one primary server per zone is allowed, and only this server loads and hosts the master copy of the zone. In addition, this server is also the only one allowed to process

service. Dynamic Host Configuration Protocol (DHCP) 4. The first attempt at breaking up IP address space used classfull addressing to provide address ranges of differing sizes. 5. Prior to the introduction of the Domain Name System, computers used HOSTS files to map human-readable named to IP addresses. 6. A(n) subnet mask is used to separate the host address portion of an IP address from the network address. 7. The

When you are using DNS or DHCP you should keep in mind that they are very large roles and you should only use them if you need to address a large number of PC’s and you cannot manually address them yourself. In fact you should probably only use DHCP if you are working with upwards of 100 terminals otherwise you should manually address them because DHCP does consume a lot of resources and therefore you should avoid using it. The reason that it consumes so much is because of the fact that you are running

but not a name, then the most likely reason for failure to connect is a name resolution problem. Name resolution can fail for NetBIOS or DNS host names. If the client operating system is NetBIOS dependent, the VPN clients should be assigned a WINS server address by the VPN server. If the client operating system uses DNS preferentially, VPN clients should be assigned an internal DNS server that can resolve internal network host names. When using DNS to resolve internal network host names for VPN
