Time-to-Live (TTL)

The DNS System powers the Internet as we know it today and is responsible for converting domain names into IP addresses and for placing them on the correct hosting server. But the DNS system would have been just a theoretical concept, if TTL was not presented.

TTL is an acronym for Time To Live and refers to the capability of the DNS servers to cache DNS records. It represents the amount of time that a DNS record for a certain host remains in the cache memory of a DNS server after the latter has located the host's matching IP address.

By specifying TTL settings for a particular domain's DNS records, webmasters define the frequency of website content updates. The longer the TTL value is, the faster the domain resolution time periods will be. The TTL value can be set from one to several hours, if you are not planning any changes to your domain's DNS records in the meantime. If you need to make such changes, you will have to decrease the TTL value entry to several minutes to avoid any outdated data on your website.

TTL values are entered as seconds and the common TTL time value is 86400 seconds, which is virtually equal to one day (24 hours). With this value set for your domain, any changes to your DNS records will be reflected online in up to 24 hour

I think the forward look-up zone is use to convert host name to ip address of a pc in our network

Specialized Device for exchanging data amongst class based Networks & Subnetted (multiple parts of one network) is Router.

A DNS address is the address to a server that converts a URL to an IP address. Most DNS address' are provided by your ISP, although there are many free DNS servers available.

could somebody help me out on this one i can't figure it out to?

there is no difference between a primary and secondary DNS server except that in normal operation the primary is the one that is tried first if that dosent work then the secondry is used, just list any 2 of the 3 you have as primary and secondry

NS 2 RFC 1035

Name Server. Defines the authoritative name server(s) for the domain (defined by the SOA record) or the subdomain.

SOA

DHCP is Dynamic Host Configuration Protocal. It assings IP addresses to the needed computers in a network dynamically.

DNS is Domain Naming System(Service) It is system for naming computers and network services that is organized into a hierarchy of domains. DNS naming is used in TCP/IP networks, such as Internet, to locate computers and services through user friendly names.

One of the Windows Server operating systems.

PHP can be installed with Microsoft's IIS web server as an ISAPI filter, or you can install the WAMP server under Windows that contains the Apache web server, the PHP interpreter, and mySQL.

There are others as well, such as the Xitami web server, etc., that work equally well with PHP under windows.

Domain: A security boundary for the network On a local area network (LAN), a domain is a subnetwork made up of a group of clients and servers under the control of one central security database. Within a domain, users authenticate once to a centralized server known as a domain controller, rather than repeatedly authenticating to individual servers and services. Individual servers and services accept the user based on the approval of the domain controller. Organisational Unit: A part of Active Directory used to Organise and Manage the objects of AD An organizational unit (OU) is a subdivision within an Active Directory into which you can place users, groups, computers, and other organizational units. You can create organizational units to mirror your organization's functional or business structure. Each domain can implement its own organizational unit hierarchy. If your organization contains several domains, you can create organizational unit structures in each domain that are independent of the structures in the other domains. The term "organizational unit" is often called as "OU" in casual conversation. "Container" is also often applied in its place, even in Microsoft's own documentation. All terms are considered correct and interchangeable.

Windows Server 2008 has five Active directory related roles. below are the list

1. Active Directory Domain Services (Identity): AD DS it provides the functionality of an identity and access (IDA) solution for enterprise networks. It also provides the mechanisms to support, manage, and configure resources in distribution network environments.

2. Active Directory Lightweight Directory Services (Applications): AD LDS formerly known as Active directory application mode (ADAM), provides support for directory-enabled applications.

3. Active Directory Certificate Services (Trust): AD CS to set up a certificate authority for issuing digital certificates as a part of a public key infrastructure (PKI) that binds the identity of a person, device or service to corresponding private key. Certificates can be used to authenticate users and computers, provide web-based authentication, support smart card authentication, and support application, including secure wireless n/w, vpn, Ipsec, EFS, and more.

4. Active Directory Rights management Services (Integrity): AD RMS is an information-protection technology that enables you to implement persistent usage policy templates (for documents) that define allowed and unauthorized use whether online, offline, inside, or outside the firewall.

5. Active Directory Federation Services (Partnership): AD FS enable an organization to extend IDA across multiple platforms, including both window and non-windows environments, and to project identity and access rights across security boundaries to trusted partners.

There is nothing that specifically stops you from using Windows XP as a server. However, the TCP/IP stack has been "crippled" to limit the number of simultaneous connections, ostensibly to prevent the spread of malware. This would stop you from effectively using a Windows XP as a large-scale server. There are patches to improve such functionality.

; and code integrity : By centralizing business logic on an individual or small number of server machines, updates and upgrades to the application for all users can be guaranteed. There is no risk of old versions of the application accessing or manipulating data in an older, incompatible manner. ; Centralized configuration : Changes to the application configuration, such as a move of database server, or system settings, can be done centrally. ; Security : A central point through which access to data and portions of the application itself can be managed is considered a security benefit, devolving responsibility for authentication away from the potentially insecure client layer without exposing the database layer. ; Performance : By limiting the network traffic to performance tier traffic, it is perceived that the client-server model improves the performance of large applications in heavy usage environments. ; Total Cost of Ownership (TCO) : In combination, the benefits above are considered to represent a cost saving to a company when developing enterprise applications. In practice, however, the technical challenges of writing software that conforms to that paradigm combined with the need for software distribution to distribute client code somewhat negate these benefits. ; and code integrity : By centralizing business logic on an individual or small number of server machines, updates and upgrades to the application for all users can be guaranteed.
