ROUTING IN CISCO.

Router


It is a device used to communication between two

different networks.
􀂇 Routing

It is process of sending the data packets through the

best path to reach the destination.


􀂇 Default Gateway

It gives the exit point (or) entry point to reach the destination.
 
Use of Routing and Remote Access Service in


Windows Server 2003

􀂇 Routing and Remote Access is a service that

performs routing as one of its multiple processes.
 
What is Network Address Translation ?


􀂇 Provides access to the Internet from a

protected private address range

􀂇 Translates Private IP􀂶s to Public IP􀂶s & vice-versa for

outgoing and incoming traffic

􀂇 Hides private IP address range from the Internet

􀂇 Can be used with DHCP or can be configured to assign IP to Client
 
5


IP = 10.0.0.3

IP = 10.0.0.4

IP = 10.0.0.5

1. The client sends the packet to the computer running NAT

4. The computer running NAT determines the destination,

changes the packett header, and sends the packett tto the client

2. The computer running NAT changes the packet header and

sends the packet over the Internett tto the Web server

3. The Web server sends a reply to the computer running NAT

Web Server

IP = 66.11.10.12

Computer Running NAT

Internal IP = 10.0.0.1

External IP = 202.153.32.1

Clientt Computers Internet
 
What Is a DHCP Relay Agent?


􀂇 A DHCP Relay agent is a computer or router

that listens for DHCP Broadcasts from DHCP

clients and then relays those messages to DHCP Servers.
 
1-Client 1 broadcasts a DHCPDISCOVER ppaacckkeett


2-Dhcp Reelay agent forwards the DHCPDISCOVER message to the DHCP server

33 Server sends a DHCPOFFER message to the DHCP rellay agent

44 Rellay agent broadcasts the DHCPOFER Packet

55 Cllient1 broadcasts a DHCPREQUEST packet

66 Rellay agent forwards the DHCPREQUEST message to the DHCP serer
77 Server sends a DHCPACK message to the DHCP rellay agent

88 Rellay agent roadcasts the DHCPACK packet

RIS(Remote Installation Services)

􀂇 BINL (Boot Information Negotiation Layer)


Responsible for RIS Process. Informs the Sequence of

servers to all Clients.

􀂇 TFTP (Trivial File Transfer Protocol)

Responsible for downloading OS Files from server to

clients

􀂇 SIS (Single-Instance Storage)

Responsible for saving all common files of multiple

images in Single folder Called SIS Common Store
 
Types of Installations


􀂇 Attended

If we manually attend the client to answer all Questions

like Name, Org Name, Product Key, Time Settings etc.

􀂇 Unattended

If we don􀂶t attend the Client to answer those Questions

instead of us Answer File Will answer all the Questions
 
Known & Unknown Clients


􀂇 Known Clients

If the Client Information (GUID) is present in Active

Directory.

􀂇 Unknown Clients

If the Client Information (GUID) is not present in Active Directory.

Profile is a User-State Environment

Profile contains Personal Settings of the User

like: 1.Documents & Settings

2.Desktop Settings

3.Start Menu Icons

4.Shortcuts

5.Application Data

6.Internet Settings

7.Favorites etc

3

PROFILES

􀂇 Local Profile

A local user profile is created the first time you

log on to a computer and is stored on a computer's local

hard disk. Any changes made to your local user profile

are specific to the computer on which you made the

changes.

4

PROFILES

􀂇 Roaming Profile

A roaming user profile is created by your system

administrator and is stored on a server.

This profile is available every time you log on to any

computer on the network. Changes made to your

roaming user profile are updated on the server.

5

PROFILES

􀂇 Mandatory Profile

A mandatory user profile is a roaming profile that can

be used to specify particular settings for individuals or

an entire group of users. Only system administrators

can make changes to mandatory user profiles.

Home Folder

􀂇 Home Folder is a centralized location of the users

personal files (data)

􀂇 Home directories and My Documents make it easier for

an administrator to back up user files and manage user

accounts by collecting many or all of a user's files in one

location

9

DISK QUOTA

􀂇 You can use disk quotas on drives formatted with

the NTFS file system to monitor and limit the amount of

disk space available to individual users.

􀂇 Disk quota tracks and control disk space usage for NTFS

Partitions Prevent further disk space use and log an

event when a user exceeds a specified disk space limit.

What are Permissions?

􀂇 Permissions define the type of access granted

to a user, group, or computer to access resource

objects.

􀂇 Permissions can be applied to resources objects such as

files, folders, and printers

Like: Privilege to read a file, delete a file, or to create a

new file in folder.

􀂇 Permissions can be assigned to users and groups in

Active Directory or on a local computer

3

4

What Are Shared Folders?

􀂇 You can share only folders, not files

􀂇 Default permission on shared folders is Everyone, Read

􀂇 When you copy or move a shared folder, the folder is no

longer shared

􀂇 To hide a shared folder, include a $ after the name of

the shared folder

􀂇 Users access hidden shares by typing the UNC path

5

Types of Permissions

􀂇 Share Level Permissions:

􀂱 Can be Implemented on NTFS and FAT partitions

􀃭 Applies to Share Folders only and can be access from

Network

􀃭 Share Permissions can be set only on Drives and

Folders

􀃭 Different Share Permissions are Read, Change, Full

Control

6

Types of Permissions

􀂇 Security Level Permissions:

􀂱 Can be Implemented Only on NTFS partitions

􀃭 Applies to Local NTFS Drives only

􀃭 NTFS Permissions can be set on Drives, Files and

Folders

􀃭 Different Permissions are Full Control, Modify, Read

& Execute, Write, Read, List Folder Contents

􀃭 File permissions override folder permissions

􀃭 Creators of files and folders are their owners

7

􀂇 When you copy files and folders, they

inherit the permissions of the destination folder

􀂇 When you move files and folders to a different partition,

they inherit the permissions of the destination folder

􀂇 When you move files and folders within the same

partition, they retain their permissions

What Is Offline Files?

􀂇 Offline Files is a document-management

feature that provides the user with consistent online

and offline access to network files.

􀂇 Advantages of using Offline Files:

􀂱 Support for mobile users

􀂱 Automatic synchronization etc

10

How Offline Files Are Synchronized

􀂇 Disconnected from the network

􀂱 Files are synchronized at logoff. The user

works with the locally cached copy

􀂇 Logged on to the network

􀂱 Files are synchronized at logon. The user works with

the network version of the files

􀂇 If a file has been modified in both locations

􀂱 The user must choose which version of the file to

keep or to rename one file and keep both versions
