Server Support

Active directory is a directory service / database which contains all the information related as part of domain. Like server / computer / users / groups and etc. All the entities are part of domain are call it as objects. So this ADS service will relate /integrate all the object in AD. This is same like our NDS in NT4X but NDS we cannot edit / update from anywhere. Since ADS allow administrator to edit the objects from any where we are calling this as a ACTIVE DIRECTORY.

For small sites where you need mail, but not a powerful exchange server.

A forest is a collection of multiple trees that share a common global catalog, directory schema, logical structure, and directory configuration.

Trees are collections of one or more domains that allow global resource sharing. A tree may consist of a single domain or multiple domains in a contiguous namespace

In clustering External network is Public Network.

There are two types of network in Clustering.

1) Private Network---- For Heartbeat connection

2) Public Network (external Network)

Scope determines which IP addresses are provided to the clients. Scopes should be defined and must be activated before DHCP client use DHCP server for its dynamic IP configuration - In simple word scope is a set of IP address range that administrator want to assign to the devices in the network.

LDAP for directory sercices and kerberos for Authentication.

Domain Name server is server role which resolves IP address into Domain name of devices in the network. Where as Domain is a name that locate organisation or other entity on the internet.

Please share your answers.

Question is not clear about which protocol - But Protocol i set of rules and regulations and these rules are different for every protocol, for example TCP/IP etc

ISP stand for Internet Service Provider for example AOL, BT, Virgin are examples of ISPs. The ISP is housed in a building called a data center, which contains all of the computing and networking computer that runs the ISP.

Requirement for Active Directory

1)NTFS partition with enough Free space

2)Administrator's username and password

3)Correct Operatiing system version

4)Nic

5)Properly configured TCP/IP (IP address, subnet mask and - optional -default gateway)

6) Net Work Connection(Through Switch or Via Another Computer with Crossover cable)

7) DNS Server

8)Domain name that you want to use

9)The Windows 2000 or Windows Server 2003 CD media

Work Of Active Directory: Active Directory store information and data about networks and domains, Network Users.

This is a common problem faced by a everyone working in support team.

1. don't try to argue with him.

2. try to understand the issues or problems he is facing.

3 .don't promise him heaven and earth.

Finally keep a cool head don't concentrate on what he is saying and just concentrate on the solution.

As a support staff your duty is to focus on the best possible solution.

Don't get carried away.

You back up active directory by doing a system state backup with either windows back up or a third party backup provider (e.g. Symantec backup exec). When you perform a system state backup the ntds.dit file is backed up and the ntds.dit file is the file which active directory is stored in. It is not possible to just backup the ntds.dit file you must do a system state back up.

There are three types of Active directory they are

1) Schema partition

2) Domain Partition

3) Configuration and another new partition is application partition it is introduced windows Server 2003 onwards.

The directory database is ntds.dit contains on the folder: c:windows

tds and there is a folder sysvol contains information of registry setting and group policy settings.

Kerberos is an authentication machine which provide authentication to acessing of special type of secured networks it is bascially used in bank accounts

In order to run a computer, several data locations needs to be referenced in a short period of time. Such data locations consists are in relatively well predictable clusters. This concept of frequently accessing same or related value storage locations is known as Locality of Reference. It is also known as "principle of locality" / "locality principle".

Few special cases of locality are as follows:

1. Temporal locality,

2. Spatial locality,

3. Equidistant locality

4. Branch locality.
