Unit 8 Homework
Unit 8 Assignment 1
DNS is a server based distributed database management system that translates domains host’s names to IP Addresses. It also allows a computer host or a client to use words instead of numbers to request information from a server or a client. You can get words or numbers to get the information from servers.
Unit 8 Assignment 2
In Windows NT, when you make a change to the Security Accounts Manager, the change is applied directly to the Primary Domain Controller and is later replicated to each Backup Domain Controller. In an Active Directory multi-master replication environment, each domain controller contains a copy of Active Directory, not just the information for a single domain. When a change is made to Active Directory, the change is applied to whatever domain controller is the closest, and is then replicated to the remaining domain controllers. This prevents a designated Primary Domain Controller from being overburdened.
Centralization sums up a primary reason for implementing Active Directory. The Active Directory structure makes it possible for you to achieve truly centralized management of users, regardless of how big the client’s network has become. In Windows NT a domain is a completely independent entity, and while it's possible to create a trust relationship between domains that exist on a common network, the domains are never truly integrated with each other because there is no higher authority that manages the domains.
The domain level is the highest level of abstraction in Windows NT. The highest level of abstraction in Windows 2000 and 2003 Server is the “forest,” which is basically a collection of domains. Microsoft chose to call this Active Directory a forest because you can place domains into the forest, and you can place entire trees of domains into it. A domain tree consists of a parent, child, grandchildren, and great grandchildren domains. You can have as many layers of subdomains within a domain as trees have limbs.

All the US office users will be put together in a section in the Active Directory; I will then set the users rights and permission to where it can only be used for work related applications only. The US office personnel will no longer be able to change their workstations, like the backgrounds, screensavers, and etc. without contacting the System Administrator. Also disable all add-on applications that will cut down on the Bandwidth usage. Since these applications don’t stop automatically until you disable them.
