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 IPs to Public IPs & 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

Internal IP = 10.0.0.1
External IP = 202.153.32.1

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

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

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

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

Different Permissions are Full Control, Modify, Read

File permissions override folder permissions
Creators of files and folders are their owners

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

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

What Is Fault Tolerance?
The ability to survive hardware failure
Fault-tolerant volumes provide data redundancy
Fault-tolerant volumes require dynamic disks
Fault-tolerant volumes are not a replacement for
backup
8
What Is a Simple Volume?
Contains space on a single disk
Can be created only on dynamic disks
Can be extended if formatted with NTFS
Fault Tolerance is not available
Spanning is not available
