        There are vast web pages and forums dedicated to domain investing and how to sell domains. Nobody is
      showing these people the big picture, merely incomplete pieces to the puzzle that might generate a few small
                                            sales and big disappointments.

                                                     The Uses of the Active Directory
                                                                    By Peter Garant



  With the ever increasing amount of data moving across large networks, it behooves the network
systems administrator to oversee the proper function of these elements, not to mention implement the
correct security measures. One helpful tool is the Active Directory.

 Developed in 1996 by Microsoft, the Active Directory is the primary method by which Windows
operating systems amasses information about domains, and also monitors them. In recent years the
function has been increased to allow it to facilitate and view online data flows.

The Structure of the Active Directory

 Because it was devised to make accessible all the pertinent objects in the network, the directory was
structured in an easy to understand hierarchical structure. There are multiple viewing levels: forests,
trees and domains/objects.

 The forest is where every tree and domain can be viewed; dropping to the tree level, you will see that
it contains one or more domains. Domains or objects have no deeper level.

 There are three main categories: Resources, which cover hardware devices like printers and
scanners; the other two are Servers and Objects, which are primary components of both the network
and the domain.

 The Active Directory is especially useful for managing objects. An object can be defined as any
element that can contain another object. Every object has its own properties or schemas, which can be
accessed and modified.

How the Active Directory Works

 What makes Active Directory so important for a systems administrator is that it makes the updating
and upgrading process a virtual one step process. For example, you need to install a new security
application. If there are several computers in the network, the procedure would be tedious, but Active
Directory, via its forest structure, makes this easy; you just update one object and it applies to all.

 The structure is also flexible enough to allow for making changes to specific objects. Because each
has its own schema, then the administrator can assign a particular task to a user and use certain
software without giving access to everyone.

Trusts

 To determine access levels, the Active Directory utilizes two elements: transitive trust and one way
one transitive non trust.

 The transitive trust, when used, signifies that the administrator has allowed users admission into the
other’s domain and/or tree. The one way one transitive non trust, on the other hand, means entry into a
tree or domain but not admission into other domains.

 This situation often happens when a network system administrator accesses the domain of any
number of users, but the end user cannot go beyond the domain assigned to him/her. This can be very
important for administrators when it comes to checking out problems with a user’s domain.

 These are just some of the things that one can use with Microsoft’s Active Directory. While they can
be quite technical, they can, once learned, make management of information and data, as well as
performing security checks and software upgrades, much easier.

 It is for this reason that usage of Active Directories has become part and parcel of servers and
networks with Windows operating systems.

                                Why You Should Use Articles Directory - The Benefits
                                                        By Abhinav Srivastava



 There are many different reasons why you should submit your articles to an articles directory. Articles
directories are the hottest form of advertising, promotion and the best way to promote your website.
With so many people logging onto the internet and the freelance writing booming, it is no wonder that
articles directory sites are so very much in demand. Not only are articles directory sites simply the best
way to drive more traffic to your website, but if you are a brand new writer looking for an outlet, there is
no better way to let other people get to know you than by submitting your writing to an articles
directory.

There are a few things that you need to know when you are looking for a good articles directory to
submit your articles. First, you need to look and see how long the articles directory website has been
around. This can be an important aspect when it comes to choosing this directory. If the articles
directory website has been around for a long period of time, such as five years, you know that it is a
credible website. When you are submitting advertising articles, you are going to get some feedback. If
the articles directory website has only been around for six or seven months, you should look for
another site. The entire point of submitting articles to an articles directory especially when you are a
webmaster is to drive traffic to your website. This is best done with an experienced directory.

Next, you always want to make sure that on the contact information is listed on the article directory
website. This is to insure that if you have any problems with your submission, you can contact the
directory representative. Most articles directories are effective, but every once in a while you may run
across one that is less than stellar. Be sure to have contact information in case you have questions
about your submission so that they can be answered promptly.

Finally, you always want to make sure that you read the articles directory website guidelines. This is a
good idea to do even before you start to write your articles so you can comply. Some articles directory
websites have a lot of rules and regulations. It is best to know what is expected from your writing
before you begin to write articles for certain article directory websites, so that you do not end up
wasting time.
