Active Directory – Container objects

Continue from my previous post... http://serveradministrators.blogspot.com/2011/06/active-directory-components.html

 

Container Objects:-

1. Forest

2. Domain Trees

3. Domains

4.  OU’s

Forest:-

             The largest container objects with active directory are forest. The forest container defines the fundamental security boundary within the Active directory. Which means that users can access resources across an AD forest using the single logon / password combination additional logon would be?

Required to access resources across more than one forest.

             To improve the efficiency of active directory, it divides information into multiple partitions also called naming contexts (NCs). Each domain controller copies of the ntds.dit database file will contain a minimum of three Naming contexts. The following two naming context are replicated forest-wide and are thus stored in the ntds.dit file on every domain controller in a forest.

1.       Schema NC (or) Schema Partition

2.       Configuration partition (or) configuration NC

Schema NC:-

                The schema partition or schema NC contains the rules and definitions that are used for creating and modifying object classes and attributes within active directory.

Configuration Partition:-

                The configuration partition or configuration NC contains the information regarding the physical topology of the network as well as other configuration data that must be replicated throughout the forest.

          Because the schema NC is replicated forest wide, each AD forest has a single schema that is shared by every domain and domain tree within the forest. The information in the configuration NC is similarly shared by all domains in a single forest.

                Each domain controller also stores a copy of the domain NC, which is replicated to each DC within a single domain. The domain NC consists of users, computer and other resources information for a particular active directory domain.

In my next post I will explain about components of Domain trees, domains and OU’s.

Active Directory Components

                             Each component in the active directory can be categorized as either container object or leaf object.

Container object is one that can have other objects. It can be additional container objects as well as leaf objects.

Leaf objects is usually refers to a resources such as a printers, folders, user or groups.

Container objects like forest, domain trees, domains and OU's. 

I will post in detail about container object at later post..

How to test IPV6 connectivity

IPV6 is the next and new generation of IP address. This technology is implementation due to enormous growth of internet users.  Now today (June 8, 2011) is the IPV6 day. In this day most of the websites are they provide content IPV4 and IPV6, the process conducted by ISOC (the Internet society). The test conduct for a day, it will end on June 9, 2011. We can also check the connectivity by this http://test-ipv6.com/ website.

VB script to view system serial number

Copy the below code and save it as filename.vbs extension. then execute it

ComputerName = InputBox("Enter the name of the computer you wish to query")

 

winmgmt1 = "winmgmts:{impersonationLevel=impersonate}!//"& ComputerName &""

 

'WScript.Echo winmgmt1

 

Set SNSet = GetObject( winmgmt1 ).InstancesOf ("Win32_BIOS")

 

for each SN in SNSet

        MsgBox "The serial number for the specified computer is: " & SN.SerialNumber
