MCITP: Profiles

2011-03-15T05:45:00.000-07:00

PROFILES:

Profile is a user state environment. Profile contains personal settings of the user like

Documents, Desktop Settings
Start Menu Icons, Short Cuts
Application Data, Downloads
Contacts, Favorites.
Pictures, Music, Video etc.

We are having 3 types of profiles.

Local User Profile
Roaming User Profile
Mandatory User Profile

Local User Profile: A local user profile is created the first time you log on to a computer and it is stored on a computer local hard disk at SAM data base.

Any changes made to your local user profile are specific to the computer on which you made the changes.

Roaming User Profile: Your roaming user profile is created by your system administrator and it is stored on server.

This profile is available every time you log on the any computer on the network.

Changes made to your roaming user profile are updated on server.

Mandatory User Profile: A mandatory user profile is a roaming profile.

mandatory profiles are fixed profiles in which the user changes will not be saved.

Only administrator can make changes to mandatory profiles.

How to create user account using with Command Prompt?

Go to Command Prompt --> dsadd user cn=user name, cn=users dc=domain name, dc=com -pwd (password)

cn = canonical name

MCITP: Permissions

2011-03-15T05:29:00.000-07:00

Permissions:

Permissions define the type of access granted to a user, group or computer to access resources.

Permissions can be applied to resources such as files, folders and printer/scanners.

Permissions like privilege to read a file, delete a file or to create a new file in folder.

We are having two types of permissions:

Security level permissions
Share level permissions

Security level permissions:

Can be implemented only on NTFS partitions.
Security or NTFS permissions can be set own drives, folders and files.
By default , security permissions will be inherited from its parent drive or folder.
File permissions override folder permissions.
Creator of file and folders are the owners.
Different security permissions are : Full control, Modify, Read & execute, write, read, list folder contents.

Share level permissions:

Cab be implemented on NTFS and FAT partitions.
It can be set on drives and shared folders but not files.
Different share permission are : Read only , Contributor, Co-Owner

What are the shared folders?

Shared folder can be access from network
When you copy or move a shared folder the folder will no longer shared.

MCITP:USERS

2011-03-15T05:15:00.000-07:00

USERS:

We are having two types of user accounts:

Local user accounts
Domain user accounts

Local User : A user account created in local database of a computer
                  Local users are generally used in workgroup model computers
                  Local user can login in only the respective computer.
Domain User : A user account created in Active Directory database.
                      Domain user are used in Domain model computers.
                      Domain user can logon to any computer in the domain.

MCITP: CLIENTS & MEMBER SERVERS , Domain

2011-03-15T05:10:00.000-07:00

Client: A computer joined in the network with client operating system is client.

Client operating systems like windows vista, windows xp, window 2000 professional etc.

Member Server: A computer joined in the network with server operating system is member server.

Server Operating systems like windows 2000 server, windows NT, Windows 2003, windows 2008 serve etc.

Domain :

Domain means logical boundry of computers, without domain controller we are not form a domain.

In domain we are having atleast one domain controller and domain represented by traiangle.

MCITP-Day 3: Requirements for Active Directory Services and User Accounts

6. DNS Server.

Clients & Member Servers:

Clients: A computer joined in the domain with client operating system is called as Client.

Client Operating Systems like : Windows 2000 Professional, Windows XP, Windows Vista, Windows 7

Member Servers: A computer joined in the domain with Server Operating system is called as member server.

Member Operating Systems like : Windows NT, Windows 2000, Windows 2003 and Windows 2008 Server

Domain: What is the Domain?

Domain means logical boundary of computers. Without domain controller we are not form a domain.

In domain we are having at least one domain controller and domain represented by triangle.

USER ACCOUNTS

We are having two types of user accounts.

Local User
Domain User.

1. Local User:

A user account created in local database of computer.
Local Users are generally used in work group model computers.
Local Users can log on only on the respective computer.
Local Users data can store in SAM data base. (SAM : Security Accounts Manager)

3. Domain User:

A user account created in Active Directory Database.
Domain users are used on domain model computers
Domain users can log on to any computer in the network

MCITP - Day 2 -Topology

2011-03-04T01:15:00.000-08:00

TOPOLOGY is one of the requirement for network.

Topology means arrangement of computers or structure of computer or design of the computer.

Types of Topology:

Physical Topology:

How devices are connected to the network through the actual cables that transmit data, or the physical structure of the network, is called the physical topology.

Physical Topology are visible we are having diffrent physical topoloy

BUS Topology

A bus topology consists of a main run of cable with a terminator at each end

Advantages of a Bus Topology

Easy to connect a computer or peripheral to a bus.
Requires less cable length than a star topology.

Disadvantages of a Linear Bus Topology

Entire network shuts down if there is a break in the main cable.
Terminators are required at both ends of the backbone cable.
Difficult to identify the problem if the entire network shuts down.

RING Topology

A star-wired ring topology may appear (externally) to be the same as a star topology. Internally, the MAU (multistation access unit) of a star-wired ring contains wiring that allows information to pass from one device to another in a circle or ring .The Token Ring protocol uses a star-wired ring topology.

STAR Topology

A star topology is designed with each node (file server, workstations, and peripherals) connected directly to a central network hub or concentrator
Data on a star network passes through the hub or concentrator before continuing to its destination. The hub or concentrator manages and controls all functions of the network. It also acts as a repeater for the data flow. This configuration is common with twisted pair cable; however, it can also be used with coaxial cable or fiber optic cable.
The protocols used with star configurations are usually Ethernet or LocalTalk. Token Ring uses a similar topology, called the star-wired ring

Advantages of a Star Topology

Easy to install and wire.
No disruptions to the network when connecting or removing devices.
Easy to detect faults and to remove parts.

Disadvantages of a Star Topology

Requires more cable length than a linear topology.
If the hub or concentrator fails, nodes attached are disabled.
More expensive than linear bus topologies because of the cost of the concentrators.

MESH Topology

It similary like tree topology check bellow.

TREE Topology

A tree topology combines characteristics of linear bus and star topologies. It consists of groups of star-configured workstations connected to a linear bus backbone cable. Tree topologies allow for the expansion of an existing network, and enable schools to configure a network to meet their needs.

Advantages of a Tree Topology

Point-to-point wiring for individual segments.
Supported by several hardware and software venders.

Disadvantages of a Tree Topology

Overall length of each segment is limited by the type of cabling used.
If the backbone line breaks, the entire segment goes down.
More difficult to configure and wire than other topologies.

2. Logical Topology:

Logical Topology (also referred to as Signal Topology) is a network computing term used to describe the arrangement of devices on a network and how they communicate with one another.

Logical topologies are bound to network protocols and describe how data is moved across the network

in logical topology we are having two models.

* Work group Model or Peer-To-Peer model.
** Domain Model or Client Server Model

*Work group Model or Peer-To-Peer model.

If you are installing any operating system default your computer is workgrop model

In Work group Model one computer does not depend on any other computers.

This work group machines also called as stand alone computers.

In work group model we are creating local user accounts.

In work group model we are suing SAM database , SAM stands for Security Accounts Manager.

** Domain Model or Client Server Model

Active Directory:

Active Directory is directory service which contains information of all user accounts and shared resources on a network.

Active Directory is a centralized Hierarchical database.

Purpose of Active Directory:

Active Directory provides user log on and authentication services using KERBEROS protocol.

To centralize and de-centralize the resource management

To centrally organize and manage user accounts, computers, groups and networking resources.

Enables authorized users to easily locate network resources.

MCITP-Day 1 (Networking Basic Information)

2011-03-02T23:40:00.001-08:00

What is Network?

Inter connection of devices is Network

What is Networking?

Communication between interconnected devices.

Types of Networks: We are having 3 types of Networks.

1. LAN : Local Area Network.

Operate within a limited geographical location (Within Room, Office, Building or campus, university)
Provides full time connectivity to local services.

2. MAN: Metropolitan Area Network

Spans with in City.
Provides full time and part time connectivity

3. WAN: Wide Area Network

Operate over a large geographical location (Country to Country, City to City, State to Sate...etc different locations)
Provides full time and part time connectivity

Requirements of Network:

P.C/Devices
O.S (Operating System)
NIC (Network Interface Card)
(Hub,Switch and Routers)
Media (CAT cable and RJ45 Jack)

Network Requirements 2: O.S (Operating System):

O.S means Operating System. It is interface between user and device.

We are having two types of Operating Systems.

1. Server Operating System

2. Client Operating System

2.1 Server Operating System:

Server Operating System is called as Multi User Operating System and Network Operating System.

What is mean by server? , Server provides services.

so Server Operating Systems provides services (We can see what are the services in further briefly)

2.2 Client Operating System:

Client Operating System also called as a Single User Operating System and Desktop Operating System

What is mean by client? , Client access the services.

so Client Operating System access the services from Server.

Network Requirements 3: NIC (Network Interface Card)

The Network Interface Card is frequently called as NIC. It forms an interface between the networked device (computer) and the Ethernet (LAN).

Network Requirements 4: Hub, Switch, Router.

Hub: It is generally used to connect all devices on a network , so that they can communicate with each other.

It always Broadcasting.

Switch: Like Hub, it is also used to connect all devices on a network, so that they can communicate with each other.

It do first Broadcasting and from second time onwards it will do Uni cast.

Router: Router is device which allows communication between two or more different networks present in different geographical locations.
