Networking
NETWORKING (Server 2003)
Definition
It is the collection of Hardware & Software which enables two or more computers to communicate & to share the resources.
According to our computer environment, resources are divided into two categories.
Shared Resources
Hardware Resources Software Resources
E.g.: cd rom e.g.: Application software or
Hard disk etc any Application
Advantages of Networking
Ø Shared resources
Ø Low cost
Ø Communication
Ø Security
Types of Networks
Ø LAN
Ø WAN
Ø MAN
Ø INTERNET
LOCAL AREA NETWORK
By using two or more computers to configure a network in a limited geographical area is called as local area network.
WIDE AREA NETWORK
By using two or more computers to configure a network in unlimited geographical area is called wide area network.
INTERNET
Networks in a network is called internet.
TOPOLOGY
The way of configuring the network is called topology.
LAN Topologies
· BUS Topology
· RING Topology
· MESH Topology
· STAR Topology
Bus Topology
v In this topology, the systems are connected in serial fashion. In this topology, data is passed on via systems.
v In this topology, the ending point of the system is connected to the starting point of the next system and the starting point of the first system and ending point of last system is terminated with 50Ω resistor.
Advantages
Low cost Easy to design
Disadvantages
Difficult to trouble shoot More traffic generates low band width Single point of failure can collapse entire network
Ring Topology
v In this topology, the systems are connected in serial fashion and the last system ending point is connected to the starting point of the first system.
Advantages
Redundancy (double layering of cable) Easy to troubleshoot (acknowledgement process) Alternative route
Disadvantages
More expensive Difficult to design More traffic generates low bandwidth
Mesh Topology
v In this topology, the systems are independently connected to another system.
Advantages
Easy to troubleshoot Low traffic generates higher bandwidth
Disadvantages
More expensive Difficult to design
Star Topology
v In this topology, the systems are communicated to another system through network media devices such as Hub or Switch.
Advantages
Easy to design Low traffic generates higher bandwidth Easy to troubleshoot Single point of failure cannot collapse entire network
Disadvantages
More expensive
The minimum requirements to configure a LAN
Hardware Software
1. Two PCs 1. Any Operating system from Microsoft
2. Network interface cards 2. Drivers
3. Networking media devices such 3. Service
as Hub and Switch
4. Cables 4. Client
5. Connectors (RJ 45 Connector) 5. Protocol
[RJ 11 (phone)]
6. Connecting devices such as
Crimping tools
Software
Drivers
It is a piece of software which acts as a mediator between Operating system and our hardware.
Service
It is used for Microsoft file and print sharing purpose.
Client
It is used for Client to the particular Server.
Protocol
Protocol is the set of rules and regulations which controls the data transmission among the systems over a network.
Types of Protocols
à NETBEUI Protocol
à IPX/SPX Protocol
à APPLE Protocol
à TCP/IP Protocol
NETBEUI Protocol
v It stands for Network Basic Emulated User Interface.
v It is designed by Microsoft.
v It is available in all Microsoft operating systems.
v By using this protocol we can communicate Microsoft operating systems machines only.
v It is a plug and play protocol, so no configuration of this protocol is required.
v It is faster than when compared to any other protocol.
v It occupies less space.
v It is suggested for only homogeneous networks.
IPX/SPX Protocol
v It is designed by Novell organization.
v It stands for Internet Packet Exchange /Switched or Service Packet Exchange.
v It is available in Novell operating systems & Microsoft operating systems.
v By using this protocol, we can communicate Novell to Novell & Novell to Microsoft operating systems.
v A little bit administration over head.
v Some extend to heterogeneous but it is not full fledged heterogeneous typed protocol.
APPLE Protocol
v It is designed by Apple Organization.
v It is available in Macintosh operating systems.
v By using this operating system we can communicate Macintosh to Macintosh.
TCP/IP Protocol
v It stands for Transmission Control Protocol/Internet Protocol.
v It is designed by International Standard Organization (ISO).
v All operating systems support this protocol, so it is the Universal protocol.
v By using this protocol, we can communicate any operating system machine to any operating system machine.
v TCP/IP protocol becomes very much popular because it has the Routing Algorithm.
ROUTING
The process of selecting best possible route to reach the destination is called Routing.
Disadvantages
It is slower when compared with any other protocol. It occupies more space in our hard disk. Knowledge TCP/IP addressing is required.
SYSTEM ADDRESS
Physical address logical address
MAC (Media access control)
IEEE
v System address is the combination of physical address and logical address.
Physical address
v It is designed with 16 bit hexa decimal code.
Eg: 2E-3B-B1-8D-3F
v Physical address is given to Network interface cards by IEEE
(Institute of Electrical & Electronic Engineers).
Logical address
IP Address (32 bit)
· The minimum octet value is Zero.
0 0 0 0 0 0 0 0 = 0
· The maximum octet value is 255.
27 26 25 24 23 22 21 20
1 1 1 1 1 1 1 1 = 255
E.g. 21.33.45.125
v Logical address is also called IP address.
v IP address is the combination of network identification and host identification.
v IP address is 32 bit decimal coded.
v These 32 bits can be divided into 4 parts.
v Each part having 8 bits called as Octet.
v These octets are separated with period (.)
v So each octet can store a minimum value of zero and maximum value of 255.
v Class: To identify the NID & HID in particular IP address, IP
addresses are given some ranges called as Class. They are,
Class Range NID HID
Class A 1 – 126 1 3
Class B 128 – 191 2 2
Class C 192 – 223 3 1
Class D 224 - 239 Multicast Range
Class E 240 – 255 Reserved range for feature
Experiments
v Classes are classified according to the values of first octet.
Rules
§ IP address cannot start with zero & 255 and cannot end with zero and 255
§ IP addresses can always starts with Network Identification and ends with Host Identification.
à 127 is the loop back adapter address used for self checking purpose.
E.g. 127.0.0.1
Subnet Mask:
It represents that how many octets (no. of bits) reserved for network identification and host identification.
Class A 255.0.0.0
Class B 255.255.0.0
Class C 255.255.255.0
Ø If we want to assign a IP address to the particular system,
§ Syntax
My Network places→ Right click properties→
Local area connection→ Right click properties→
Select TCP/IP Protocol→ properties→
Use select the IP address→ assign the IP address and Subnet mask→ then click OK.
Ø If we want to see the IP address in CUI (character user interface),
§ Syntax:
Start→ Run→ Type cmd→ Type ipconfig
Ø If we want to see the IP address with physical address,
§ Syntax:
Start→ Run→ Type cmd→ Type ipconfig/all
Ø If we want to check the communication between two systems,
§ Syntax:
Start→ Run→ Type cmd→
Type ping < Destination address >
Eg: ping 100.10.10.3
Note: If reply comes with data packets list (TTL list) then, we decide to perfect communication between two systems.
Note: If reply comes with “request timed out” then we decide to troubleshoot in physical connections between two systems.
Note: If reply comes with “Destination host unreachable” then we decide to troubleshoot in IP addressing.
DATA TRANSMISSION
Ø All services bind to protocol.
Ø All protocols bind to NIC.
Ø TCP/IP protocol suit designed, based on OSI (open system interface) seven layers.
Ø Each layer having its own importance and these layers are Bi-directional layers i.e, whatever transmission section layer transmits that can be understandable by receiving section layer.
OPERATING SYSTEM
Definition
Operating system is the interface between user and system (computer).
According to the user interface, Operating systems can be divided into two types.
1. GUI (Graphical User Interface)

Ø This type of network is called as WORKGROUP or peer to peer network.
Ø In this network, each system having its own importance i.e, every system acts as a peer.
Ø Shared resources are distributed normally.
Ø Security provided here is called as Shared level security i.e. the user
Must and should remember the multiple passwords for accessing the
Resources.
Ø The users of the particular system cannot logon to another system because there is no centralized administration.
Ø So, this type of users we called as local users and the system acts as local system.
Ø If we want to configure a Workgroup system,

Ø If we want to see the shared resources of the particular system,
§ Syntax:
Right click My Network places→ Open→ entire Network→
Microsoft Windows Networks→ Select Workgroup→
Select system and enjoy the resources.
Hidden Share:
Run with $:
If we create a file and share it and if the “Share Name” is with ‘$’ e.g. hidden$, then the folder will not be visible for access in the Network.
Ø If we want to access such folders,
§ Syntax:
Start→ Run→ Type “\\system name\folder name$
e.g. \\mcse2\hidden$

Start→ Programs→ Administrative Tools→ Active Directory Users and Computers→ Select Users→ Select particular User→ Right click→ Properties→ Profile tab→ In “Home Folder” option, select connect and assign drive letter→ Enter the UNC path (\\Domain Controller system name\shared folder name\User name).
FILE SYSTEMS
After Switching the Power on, the system goes through these processes.
1. POST (Power On Self Test)
It checks the Processor, RAM, Display Card etc.
2. System Configuration
It checks the Configuration about Processor speed, RAM size, Hard Disk size etc.
3. Booting
The process of loading System files and Bootable files of Operating system from Secondary Storage device (Hard Disk) to Micro Processor is called Booting.
Partitions:
According to our Windows 2003 Server Operating system, we are having two types of partitions.
1. System Partition
It contains Bootable files.
2. Boot Partition (System Root)
It contains Windows folder.
o Tracks are divided into Sectors.
o Sectors are divided into Clusters.
o Data is stored in Clusters.
o Track 0 is also called as MBR (Master Boot Record).
The MBR (Master Boot Record) contains,
1. Partition information
2. Root Directory
3. Bootable Files
4. File System
Partition information:
It contains the information about Logical drives.
Root Directory:
File system writes file properties i.e. file name, file type, file location, file attributes (read, write, and archive) in Root Directory.
Bootable Files:
According to Windows 2003 Server Operating System, there are five Bootable files.
1. NTLDR
2. BOOT.INI
3. BOOT SECT.DOS
4. NT BOOT DO.SYS
5. NT DETECT.COM
FILE SYSTEM
File System is the file databases which maintains the read or write operations on a physical disk by maintaining the sector information.
Ø When the data is stored in the physical disk, it may be stored in multiple clusters.
Ø A table is created in File System. This Table maps file to the Clusters, where they are located and contains information about their sequential order. So, the file was located and read.
File System in different flavors:
1. FAT 16 (File Allocation Table – 16 Bit)
2. FAT 32 (File Allocation Table – 32 Bit)
3. NTFS (Network File System)
FAT 16:
Ø FAT 16 is also referred as FAT, is widely used in Windows NT 4.0 operating system and earlier versions of Operating systems.
Ø A table entry is 16 bits per entry.
FAT 32:
Ø FAT 32 is used to differentiate between the versions.
Ø It was introduced with Windows 95 operating system.
Ø When FAT 32 was introduced, the table length was extended to 32 bits per entry.
NTFS:
Ø NTFS File System was introduced with Windows NT 4.0 operating system and has been some improvements. Again NTFS was introduced as NTFS File System 5.0 with Microsoft Windows Server 2000 and fully supported by Microsoft Windows 2003 Server.
Ø NTFS was a Master File Team (MFT). It is similar to FAT 16 and FAT32 but, more efficient. NTFS because of having different Architecture is not readable by Windows 98 and earlier operating systems.
Ø Although Microsoft Windows 2003 Server supports FAT32 and NTFS, it is highly recommended to format using NTFS File System.
Ø NTFS File System was required, when Active Directory Service is installed.
Ø By using NTFS File System, we can have Compression, Encryption, File and Folder level Security and Disk Quotas.
Note: We can convert FAT32 to NTFS file system of particular Partition in GUI mode but, we will lose the Data of that particular Partition.
Note: We can also convert FAT32 to NTFS file system of the particular Partition in CUI mode. We would not loose the Data.
§ Syntax:
Start→ Run→ Type cmd→ Ok→ in the Command prompt type, “convert <drive letter>:/fs:ntfs “.
e.g. convert d:/fs:ntfs
Compression:
By using Compression, we can compress the contents of the particular folder or file to save the disk space.
§ Syntax:
Right click the folder→ Properties→ Advanced→ Select “Compress the Contents to save disk space”→ Ok.
Encryption:
By using Encryption, we can encrypt the data in the particular file or folder to secure the data.
§ Syntax:
Right click the folder→ Properties→ Advanced→ Select “Encrypt the data of a particular file or folder”→ Ok.
Disk Quotas:
By using Disk Quotas, as an Administrator we can assign limited disk space to a particular User.
§ Syntax:
Select particular disc→ Right click→ Properties→ Quotas→ Enable Quota management→ Select “Deny Disk space to users exceeding Quota limit.
Limit Disk space to: 
Set warning level to:
Select the Quota logging options for this volume
In logging options,
→ Select “log event when a User exceeds the Quota limit”
→ Select “log event when a User exceeds their warning level”
→ Go to Quota entry tab→ Quota menu→ New Quota entry→ Advanced→ Find now→ Select particular User→ set Disk space and warning level→ Ok→ Apply→ Ok.

Disk Management
Disk Management:
§ Syntax:
Right click My Computer→ Manage→ Storage→ Disk Management.
HDD configuration is of two interfaces.
1. Integrated Device Electronics (IDE):
IDE can have two Devices to be connected.
2. Small Computer System Interface (SCSI):
SCSI can have 32 Devices to an interface.
By using Disk Management we can create,
1. Disk Partition
2. Simple and Spanned Volumes
3. Spanned and Stripped Volumes
4. RAID Levels or Fault Tolerance
Note: We can create four Primary Partitions (BASIC)
Note: RAID - Redundant Array of Independent Disk
Note: RAID 0 - Simple + Spanned (Disk Stripping)
Simple Volume:
Combining two or more free spaces in one Hard Disk is called Simple Volume.
Minimum Hardware Requirements:
1. One Hard Disk
2. Number of IDE Controllers – 1
Spanned Volumes:
Combining two or more uneven free spaces on multiple Hard Disks is called Spanned Volume.
Minimum Hardware Requirements:
1. Number of IDE Controllers – 1
2. Hard disks – 2
Stripped Volumes:
Combining two or more even free spaces on Multiple Hard Disks is called Stripped Volume.
Minimum Hardware Requirements:
1. Number of IDE Controllers – 1
2. Hard disks – 2
Simple/Spanned Stripped
1. 
We can combine two or more 1. We can combine two or more
We can combine two or more 1. We can combine two or more
Uneven free spaces. Even free spaces.
2. Data is written serially 2. Data is written parallels.
(Serial writing).
3. Writing and Reading Data is 3. Writing and Reading Data is
Slow (Disk Performance is poor). Faster (Disk Performance is fast)
4. 
We cannot keep either Boot or 4. We cannot keep either Boot
We cannot keep either Boot or 4. We cannot keep either Boot
System Partition. or System Partition.
5. No Fault Tolerance. 5. No Fault Tolerance.
RAID 1 or Disk Mirroring:
1. Writes Data to two disks simultaneously. Writes all Data to both Primary and Mirror Disks.
2. Can use only 50% of the Disk Space.
3. Can contain any partition includes Boot and System Partitions.
4. Supports FAT and NTFS File Systems.
Note: RAID 0 is not Fault Tolerance.
Note: RAID 1 is a Fault Tolerance.
In a RAID 5 volume, Fault Tolerance is achieved by adding a Parity Stripe to each Disk partition in the volume. If a single Disk fails, Windows uses the Data and Parity information on the remaining to reconstruct the Data that was on a failed Disk.
Parity:
In mathematical method of determining, it is the number of odd and even bits which can be used to reconstruct Data.
System Tools
Disk Defragmenter:
Sometimes we create, remove, move, copy and edit files. They can become fragmented.
When a file is written to Disk, it is written to Clusters. Clusters are tiny parts of the Drive where information is stored. When a file is moved or deleted, opened, the non-contagious clusters are not removed as well thereby creating a fragment. The process of de-fragmenting removes lost Clusters and also records in a more efficient order. De-fragmentation will improve the performance of the System.
§ Syntax:
Start→ Programs→ Accessories→ System Tools→ Disk Defragmenter.
Disk Cleanup:
To remove the temporary internet files, compressed old files, empty the Recycle Bin. Disk Cleanup is provided as a utility.
§ Syntax:
Start→ Programs→ Accessories→ System Tools→ Disk Cleanup.
Chkdsk:
This Command is used to scan and fix the errors on the disk
§ Syntax:
Run Cmd→ type “chkdsk <drive letter>: and press enter.
e.g. c:\chkdsk d: (where ‘d’ is the ‘d’ partition)
BACKUP
Backup:
Backup is the plan in which recovery from sudden failures is possible.
Ø Every file contains an Archive bit as one of its hidden attributes.
Ø This attribute setting is to indicate that the file was created or after it has been modified and needs to be included in the Backup set.
Ø When the Archive bit is set to 1 that indicates the file was created or it has been modified.
Ø The Backup program will then set the Archive bit to zero which is called as clearing the Archive bit.
Ø If the file does not change by the next scheduled Backup, that file is skipped.
Ø The Archive bit settings is dependent on what type of Backup is being run.
Types of Backup:
1. Normal Backup
2. Incremental Backup
3. Differential Backup
4. Copy Backup
5. Daily Backup
Normal Backup:
Normal Backup sometimes referred to as full Backup. This Backup is the most complete type of Backup.
Ø A Normal Backup takes large amounts of time to backup.
Ø A Normal Backup clears the Archive bit of all files after backup.
§ Syntax:
Start→ Programs→ Accessories→ System Tools→ Backup→ Next→
Select “Backup Files and Settings”→ Next→ Select “let me choose what to backup”→ Next→ Select the “folder” to backup→ Next→ Choose a place to save your backup and type a name for the backup → Next→ Click “Advanced” tab→ Select “Normal” in select the type of backup→ Next→ Select “Verify data after backup” and Deselect or Select “Disable volume shadow copy”→ Next→ Select “Append this backup to the existing backups”→ Next→ Select “Now or Later” to run the backup→ Next→ Finish.
To restore a Normal Backup:
§ Syntax:
Open the saved Normal Backup file→ Next→ Select “Restore files and settings”→ Next→ In the File, Select the Desired Normal Backup File→ Next→ Advanced→ Select “Original Location” to restore file→ Next→ Select “Leave existing files (recommended)”→ Next→ Finish.
Incremental Backup:
Incremental Backup is the quickest method for performing backup of data.
Ø An Incremental Backup backups only the new files and modified files and Archive bit is set to 1, since the Normal Backup and Incremental Backup.
Ø It also clears the Archive bit of all files after Backup.
Ø To do a complete restore, we must restore the Normal Backup and previous Incremental Backups.
§ Syntax:
Start→ Programs→ Accessories→ System Tools→ Backup→ Next→ Select “Backup Files and Settings”→ Next→ Select “let me choose what
to backup”→ Next→ Select the “folder” to backup→ Next→ Choose a place to save your backup and type a name for the backup → Next→ Click “Advanced” tab→ Select “Incremental” in ‘select the type of backup’→ Next→ Select “Verify data after backup” and Deselect or Select “Disable volume shadow copy”→ Next→ Select “Append this backup to the existing backups”→ Next→ Select “Now or Later” to run the backup→ Next→ Finish.
Note: To do a complete Incremental Backup restore, we must first restore the Normal Backup and previous Incremental Backups.
§ Syntax:
After restoring the Normal Backup then,
Open the saved Incremental Backup file→ Next→ Select “Restore files and settings”→ Next→ In the File, Select the Desired Incremental Backup File→ Next→ Advanced→ Select “Original Location” to restore file→ Next→ Select “Replace existing files if they are older than backup files”→ Next→ Finish.
Differential backup:
It backup’s all that have changed or newly added files since the last full backup.
Ø When a Differential backup is used, it backup’s all files with the archive bit set to ‘1’ but, it does not clear the archive bit.
Ø By not clearing the archive bit, the Differential backup will backup the same file on two separate dates even if the file does not change.
Ø To do a complete restore, we must restore the normal backup first and last Differential backup next.
Copy backup:
Copy backup is just like Copy. It backup’s only files specified, regardless of whether the archive bit is set to ‘1’ or not & it does not clear the archive bit.
Ø They may be made when a company requires keeping data for extended length of time.
Daily backup:
It backup’s only new files or modified files on the day.
Ø It does not clear the archive bit.
System State Backup
By using System state Backup, as an Administrator we can backup Active Directory Database.
