WINDOWS 2003 SERVER (MCSE)
Networking is for sharing resources, security, communication etc.
Basic Requirements of Networking are
1) Two Systems2) Operating System
3) Network Interface Card(NIC)
4) Media (Guided Media or Un Guided Media)
5) Connectors
6) IP Address
1) The two Systems can be any configuration
e.g.: the two systems can be of Intel and AMD.
2) The Operating Systems can be of any Vendor
e.g.: the Operating Systems can be Microsoft and Linux.
3) The NIC can be of different vendors.
4) Guided Media: - A physical connectivity between systems is called guided media.
Un-Guided Media: - A logical connectivity between systems is called un-guided media.
16 bit ISA NIC (Old version) & 32 bit PCI (NIC) can communicate each other.
5) The Connectors are cable Dependent.
6) 2 types of IP versions are available.
IP V.6 (Only in Japan) IP V.4 (other).
IP ADDRESSING
IP Address
TCP/IP is unique in that the network portion of the address has not been allocated a
fixed address space. The number of bits that the network portion may use depends on the
number of network that needs to be identified. Although a governing body allocates an
original address, the network portion of the address can be extended. To identify how many of
the address bits have been extended in the network portion of the address, a subnet mask is
used.
IP Addresses are classified into 5 classes:
Class A
Class B
Class C

Class D
Class E
* To identify the IP address which class does it belongs to the first
octet is considered.
Class A: 0 127 (128)
Total Networks = 126
Total Hosts = 16.77 millions
0 and 127 addresses are reserved.
* 0.0.0.0 is reserved for Global IP Address
* 127.0.0.0 is called as Loopback Address. Used for self testing purpose.All the networking services in the Operating System run on the loopback address.
* Class A is used by the Large Organisations.
Class B: 128-191 (64)Rule: The rule of Class B is the first 2 bits of octet are reserved as 1&0
Total Networks =
Total Hosts =
The 1st valid IP Address is 128.0.0.1 to 128.0.255.254 in a single network (255 is reserved for
broadcasting)
* Non of the values are reserved in class B.
* Used by the Large and Medium size Organisation.
Class C: 192-223 (32)Rule: The rule of Class C is the first 3 bits of octet are reserved as 1, 1&0
Total Networks =
Total Networks =
The 1st valid IP Address is 192.0.0.1 to 192.0.0.254 in a single network (255 is reserved for
broadcasting)
* Non of the values are reserved in class C.
* Used by Smaller Organisations.
Class D: 224-239 (16)

Rule: The rule of Class D is the first 4 bits of octet are reserved as 1, 1, 1&0
* Class D is reserved for News Groups & News agencies. Multicasting (one to group).
Class E : 240-255 (16)Rule: The rule of Class E is the first 4 bits of octet are reserved as 1, 1, 1&1
* Class E is reserved for Research & Development.
# To identify the IP address to which class it belongs, we need to consider the 1st octet only.

WORKGROUP:
In workgroup model all the PCs in the network are independent. Where there is no centralised
database and centralised control.
There is no concept of server & client relationship.There is lack of security.
The administrative job is too high.
DOMAIN:
In domain model each PC is dependent in the network. Where there is centralised control &
centralised database.
There is a concept of server & client relationship.
There is huge amount of security.
The administrative job is too easy.

ACTIVE DIRECTORY
Active Directory is a Directory service that contains information regarding User Accounts,
Computers and resources, resources are optional. Active Directory is a centralized database
and maintains hierarchical structure of Domains. Before 1974 each vendor were using their
own Protocols to design the software. In such case communication between the vendors wasnot possible. NT 4.0 has a database size of 40 MB i.e. SAM database (Security Account
Manager). Each user created occupies 1KB of information in SAM. A maximum of 40,000
change users can be created in a single PDC. More than 40,000 change users can be created
on a single PDC, but the server performance goes down. Because the SAM database size is
fixed.
Windows 2000 as well as 2003 database size of Active Directory (NTDS.DIT) has 16 and 12
Trust relationship between the domains with in the Forest accepts. But cross forest
relationship is not possible in Win 2000 (trust). Between two forests.
Windows 2003 supports cross forest trust relationship.
Requirements for Active Directory installation.
1. Stand alone server
2. Static IP address
3. Require 200 MB free space with NTFS partition 5.0
4. Require Windows 2003 Sever CD

Forest and Domain Functional Levels
Functional level determines
- Supported domain controller operating system.
- Active Directory features available.
Domain Functional levels can be raised independently of one another.
Raising forest functional level is performed by Enterprise
Administrator
- Requires all domains to be a windows 2000 native or windows server 2003
functional levels.
Functional Levels are classified into two levels
Domain Functional Level
Forest Functional Level
Domain Functional Levels:
a) Windows 2000 Mixed Mode
b) Windows 2000 Native Mode
c) Windows 2003 Interim Mode
d) Windows 2003 Mode

PHYSICAL COMPONENTS
Logical Components of Window 2003 Server is Forest & Trees.
Physical Components:
Domain Controllers
Sites
Domain Controller is a system which is loaded with Active Directory Services in Windows
2000 or Windows 2003 server operating system.
- Stores Replicas of Active Directory Database.
- Associated with given site.
Sites are areas of good connectivity it is one of the Physical component of the Active
Directory Services.
Sites are associated with subnet mask. Subnet Mask is a Sub Division of IP Network.

They are classified into 2 sites
1. Intra Site Replication
2. Inter Site Replication
Intra Site Replication: The replication which is taking place within a single site between DC
to ADC is called Inter Site Replication.
For Replication KCC (Knowledge Consistency Checker) service is responsible.
Inter Site Replication: The Replication which is taking place between 2 different sites is
called Inter Site Replication.
BRIDGE HEAD SERVER: The server is responsible for gathering the information from one
Domain Controller. So that it can replicate to another Domain Controller (ADC)
By Default DC & ADC serves will get updated in default first site name. In site by default
one site link also configured.

ACTIVE DIRECTORY PARTITIONS
NTDS
NTDS.DIT
SCHEMA CONFIGURATION DOMAIN APPLICATION
Active Directory Service Database is stored in NTDS.DIT. This database further logically
divided into four partitions.
1. Schema Partition2. Configuration Partition
3. Domain Partition
4. Application Partition
1. Schema Partition: Schema is a design or architecture of Active Directory, where it is
built on. It provides set of rules to create or manipulate different objects only schema
administrators can modify the schema. You can modify schema partition only when
you are planning to upgrading or installing the Operating system or applications,
which is replicating to Additional Domain Controller.
Schema is also known as forest wide replication.
21
8/7/2019 MCSE Classes
22/58
2. Configuration Partition: It is one of the logical partition which maintains the
information about structure of the forest. It contains information like Domain
Controller, Sites, Sites Links and Trust relationship.
Configuration partition is the road map of Active Directory because of which users are
easily able to locate network objects. It is also called forest wide replication.
3. Domain Partition: Will maintain the information about domains specific objects. It is a
domain wide replication
4. Application Partition: It is configurable partition either it can be forest wide
replication or Domain wide replication. It maintains the information about the DNS.

Active Directory Users & Groups
There are 2 types of users
1) Local User and 2) Domain User
1. Local User: Local users are created on the client machines as well as on Member
Server. A local user cannot access all the resources in the network. A local user cannot
login onto multiple systems. He can login where account exists. A local user account
is also called as the temporary account.
2. Domain User: The domain users are created on the domain controller. The domainuser account can access any resources on the entire network. A domain user account
can be created even on a Member Server, by login as Domain Administrator. To create
Start Run dsa.msc A Domain User and Client window appears. Now you can
create user accounts.
To create a Local User Account
Login as administrator on the client machine or on the member server.

To create Domain User Accounts on Windows 2003 server. The minimum requirement is the
password is must and should be minimum of 7 characters, which includes alphabets, special
characters and numeric numbers).
3 Types of Group scopes are:
1) Domain Local Group 2) Global Group (Default) 3) Universal Group
1) Domain Local Group: Users and groups of the domain can be added as well as users and
groups of the other domains also can be added but resources of the domain only can be
accessed.
2) Global Groups: This is the default group. Users and groups of the domain can only be
added into the Global Group but can access any resources in the entire forest.
3) Universal Group: Users and groups of the domain can be added as well as users and
groups of the other domain can also be added into the Universal Group and also can access
any resources any in the entire forest. The Universal Group is available in Windows 2000 andWindows 2003 Servers only.
2 Types of Groups
1) Security Group & 2) Distribution Group
1) Security Group: To a security group Permissions can be applied, in such a case certain
mailing services will not function properly.
2) Distribution Group: To a Distribution Group Permissions can be applied, in such a case
all mailing services will function properly.
Permissions
Permissions are of 2 types.
1) Security Permissions & 2) Shared Permissions
Shared Permissions are the permissions that are applied over the network.
Security permissions are the permissions that are applied within a local machine.
Out of both these permissions Security plays major role. The permissions are of 2
Allow and Deny. Deny has highest priority rather than Allow.
The Default Permissions in Windows 2003 Server is everyone with Read only
permission in both Security and sharing permission.
The combination of permissions that are applied in both Sharing and Security will take
effect over the network. For example if Read and Write Permission are given in
Security and Read Permission are given sharing then only Read Permission will apply
over the network.

PROFILES
Profile is nothing but user personal information which consists of Desktop, Start menu,
Application Data, My Documents etc.
By default even an administrator cant view it on certain profile (Roaming Profile).
There are 3 types of Profiles in Windows 2003
1. Local Profile 2. Roaming Profile 3. Mandatory Profile
1. Local Profile: By default each and every user has a local profile automatically created. A
local profile will be saved on the local Hard disk of the PC. A local profile user cant carry his
profile where ever he logs in the entire network. A profile will be available on the particular
system itself.
* A Local Profile can be upgraded to Roaming Profile user. A Local Profile can not be
upgraded to Mandatory Profile directly.
28
8/7/2019 MCSE Classes
29/58
2. Roaming Profile: A roaming profile user can carry his profile wherever he logs in the
entire network. Because the profile is saved on the server. Whenever the user login on a
particular machine in the network the profile is downloaded from the server.
* A Roaming Profile user can be degraded back to Local Profile user.
* Roaming Profile user can be upgraded to Mandatory Profile user.
3. Mandatory Profile: A mandatory profile user cant save any information in his profile.Because this profile has read-only permission.
* A Mandatory Profile user can be converted to Local Profile user.
* A Mandatory Profile user can be converted back to Roaming Profile user.
To convert the user from a Local Profile to Roaming Profile:
Create a shared folder on the Domain Controller (Server)
Set the permissions as user with Full Control (i.e. Shared and Security)
Go to Start Programs Administrative Tools Active Directory Users and Computers
Select the User and right click Properties. Go to Profile tab and specify the profile path.

Distributed File System (DFS)
DFS brings all the shared folders in the networks which are required to a centralized location
called as the root. Because shared folders are widely distributed across network, administrator
face growing problems as they try to keep users connected to the data they need. The
Distributed file system (Dfs) provides a mechanism for administrators to create logical views
of directories and files, regardless of where those files physically reside in the network. Fault
tolerance of network storage resources is also possible using Dfs.
To a single server in Windows 2000 DFS only one root can exist, but in 2003 DFS on a single
server multiple roots can exists.
For each link in DFS a maximum of 31 targets (backup) can be created.
Backup for the root is called as a root target. A maximum of 31 root targets can be created.
The root as well as root targets can be created only on the servers operating system.
Using the Dfs Administrator Tool
This step-by step guide describes how to use the Dfs Administrator snap-in. Installation of the
Dfs service takes place automatically during Windows 2003 Server Setup. How ever, You
must configure Dfs in order for a Dfs share to be accessible to be accessible to clients.

Software Deployment
Software Deployment is used to deploy the software over the network through the server.
Group policy doesnt support .exe extension softwares over the network. Because if an
application is installed through an exe on a particular system each and every user in the
network access the application. To deploy the software over the network through group policy
the software extensions must be either .zap or .msi (Microsoft Installation). Through group
policy the softwares can be deployed in 2 ways. 1. Publish and 2. Assign. There is also an
additional option called as advanced. Through this option only service packs and patches can
be deployed to already deployed software. Through advanced option new softwares cannot
be deployed.
To convert .exe to .zap:
Create a shared folder on the drive and set the permissions (shared and security).
Past the exe software into shared folder.Open Notepad and type the following.
[Application]
Friendlyname = name of the software
Setupcommand =\\computername\sharedfoldername\softwarename.exe

Printer
A printer device is an equipment that generates hardcopy from the softcopy. Printer device
has become an essential equipment in the network. There are generally three flowers of
printer devices available in the market they are
DOT Matrix INK-JET LASER
Cost 7000/- 2,200/- 8,000/-
Ribbon 20/- Cartridge 400/- Toner 2,500/-
Print pages 1000 500 3000
Maintenance No Yes Yes
Pages/Min. 3/4 10/12 16/18
Port LPT LPT/USB LPT/USB/IEEE 802.3
There are 2 types of Printer devices.
1. Local Printer Device & 2) Network Printer Device
1. Local Printer Device: These are connected to the PC directly and PC is connected to
the network. That means the local printer devices are system dependent. A local
printer devices are easily portable. These are easy to install and configure. These
printers are connected through two ports of the machine, LPT/USB. The buffer size in
the local printer device is less, around 2 to 8 MB.
2. Network Printer Device: These are directly connected the Hub/Switch. Because
these printer devices have inbuilt NIC card. That means they are system independent.
The network printer devices are very huge in size, and they are difficult in order to
transport. But the performance of these printers is excellent. The network printer
devices are too costly. And they are difficult in installation and configuration. The
buffer size in a Network Printer Device is huge, around 32MB, 64MB, 128MB.
Network printer device installation:
Start Run type \\ of the system where the printer device is
connected.
It displays all shared resources.
Select printer icon and double the icon the network printer driver gets installed in the
Machine.
Separator Page:

The separator page gives an identity that the printout belongs to a particular department. And
all the printer devices doesnt support separator page, only certain versions of printer devices
supports. By default the separator Pages are available in the following path
C:\Windows\system32\pcl.sep and more.
For each and every printer device only one separator page can be set.
To create new/own separator page:
Open notepad and type the following.
\
\L\U IT Department
\E
Save the file with any name .sep in system32 folder.
To set the separator page:
Start Settings Printers & faxes
Right click on the printer device and go to Properties.
In the options select Advance.
Click the Separator Page button
Click the browse button.
Select the Separate Page. Click OK, OK. OK
To set the Priority Level:
Start Settings Printers & Faxes
Right click on Printer Devices and go to Properties.
Select Advanced and Specify the Priority Level (default is 1)
You can set the priority level from 1 to 99. Apply, OK
For each Printer Device only one Priority Level can be set.
There are three different types of Printouts that can be taken through a Printer Device they are
1) Local Printout
2) Network Printout3) Internet Printout
1. Local Printout: Local printouts are taken on the printer device to which the system is
connected locally. To take a local printout there is no need of a Network.
BACKUP
Backup is nothing but creating copies for the existing data. This backup varies depending
upon the organisations. Backups can be taken not only on folders and files but even of Active
Directory. The general media that is used and specifically designed for backup is Tape Drives.
In Windows NT 4.0 backups can be taken only on tape drives, where there is no alternatives
39
8/7/2019 MCSE Classes
40/58
to take backup. This problem is solved in Windows 2000 and 2003 backups, where backup
can be taken on any media. Eg: CD, HDD, Tape Drive, Pen Drive, Zip Drive etc.
Backups are of 5 types:
1. Normal Backup
2. Copy Backup
3. Incremental Backup4. Differential Backup
5. Daily Backup
1). Normal Backup: Through Normal Backup it takes each and every file as backup. Even
though the files are already been taken backup takes all files. Once the normal backup is taken
it uncheck the Archive bits for the files. Normal backup is a time consuming backup as well
as restoring also. Generally the normal backups are taken either on the 1 st day of the week or
the 1st day of the month.
2). Incremental Backup: Though Incremental Backup it takes newly created files and
modified files only. The incremental backup is generally used by the banking & financialsector where the accounts closed at the end of the day. These backups are taken every day
separately. Incremental backup is not a time consuming process. Restoring multiple
incremental backup is a time consuming process. Once the incremental backup is taken it
unchecked the Archive bits for the file.
3). Differential Backup: Through differential backups newly created files, modified files and
previous differential backup files are taken. Taking differential backup is a time consuming
process as duration exceeds (day by day). But the restore is done faster. Differential backup is
generally used by general sector where they close their accounts at the end of the month.
Differential backup is used when multiple copies exists in the last backup. Once the
differential backup is taken it doesnt uncheck the Archive bit.
System State Backup:
System state backup is backup of Active Directory. Taking system state backup is as same as
the previous topics. The difference is restoring in system state backup.
There are 2 types of restores for system state backup.
1) Authoritative 2) Non-authoritative
1) Authoritative: Authoritative restore is done when there is replication between thedomains. The Authoritative restore is used to Update Sequence Number (USN). For
every object create or delete, it updates USN value.
2) Non-authoritative: Non-authoritative restore is done when there is no replication
between the domains.
To restore the system state backup:
Restart the machine and press F8 after the POST (Power On Self Test) operation is over.
A menu appears. In the menu select Directory service Mode (Active Directory restores
Mode).
The Login screen appears.
In the login screen type Administrator as User name and password of Active Directory.
After you have done restore the backup first.After the backup is restored it prompts whether to restart the machine or not.

NETWORK ADMINISTRATION
DHCP (Dynamic Host Configuration Protocol)
DHCP server is used to assign dynamic IP address to the client machine (not to servers).
Assigning multiple systems with static IP addresses, the 4 major problems are:
1) IP Conflict
2) Different network IP address
3) Not assigning IP address to a client machine
4) Time
DHCP server is also present in Windows NT 4.0, but the major drawback of security feature
in Windows NT 4.0 DHCP is no authorisation concept. As this concept is used in Windows
2000 and 2003 DHCP server. Only the root administrator can do the authorisation in DHCP
server. Without authorising the DHCP severs it cannot issue the DHCP IP address.
The features of DHCP server are:
1) Scope
2) Super Scope
3) Multicast Scope
4) Reservations
5) Scope & Server options
6) DHCP Backup & Restore
Scope: Scope consists range of IP addresses belonging to a single network. A scope cannot
have multiple network IP addresses. We can have multiple scopes in DHCP servers.
Range: Range is nothing but pool of IP addresses.
Super Scope: Clubbing more than one scope into a super scope such that different network IP
address can be issued.
Multicast Scope: Multicast Scope is used to assign to a range of IP addresses from Class D
networks.
Reservations: Reservations are nothing but assigning dynamically static IP addresses. To do
the Reservations in DHCP we require the clients NIC cards MAC (Media Access Control)
address.

DNS (Domain Naming System)
DNS is used to resolve the host name to IP addresses and IP addresses back to host name.
DNS servers has 2 types of zones.
1) Forward Lookup Zone & 2) Reverse Lookup Zone
Forward Lookup Zone: It is used to resolve the host name to IP addresses. There can be
multiple Forward Lookup Zones on a single IP address. Forward Lookup Zone consists of
SOA (Start of Authority), NS (Naming System), Host, Alias etc. (And resource records are
available only on the domain zone)
Service Records: Service records consist of LADP, Kerberos, Global Catalogue,
Domain Name, TCP, UDP etc. (6 folders in 2003). These resource records areavailable only for the domain zones.

Reverse Lookup Zone: It is used to resolve IP addresses back to host names. There can be
only one Reverse Lookup Zone to the entire network. But it can consist of multiple pointers.
Forward Lookup Zone: There are 3 types of zones in Forward Lookup Zone.
1) Primary Zone 2) Secondary Zone & 3) Stub Zone.
Primary Zone: A Primary Zone is a master copy created in the DNS.NOTE: Primary Zone can be created either with Active Directory integrator or without Active
Directory integrator.
With Active Directory integrator: If a primary zone is created with Active Directory
integrated the zone file is saved in the Active Directory Data Store. The Administrator cannot
make any modifications to the zone.
Without Active Directory integrator: If a primary zone is created without Active Directory
integrated the zone file is saved in the DNS folder. The Administrator can make the
modifications to the zone file.
Secondary Zone: Secondary Zone is a copy (backup) and is used to copy the Primary zone.
There can be multiple Secondary Zones to a single Primary Zone, but the Secondary Zonemust not exist where Primary zone already exists. Secondary Zone maintains the total
information of the Primary zone.
Stub Zone: Stub Zone is also a copy of Primary zone but Stub Zone maintains only 3 records
information of the Domain zone or 2 records of the other zones. The 3 records are 1) SOA, 2)
NS and 3) Host. Stub Zone is available only in windows 2003 DNS server.
Requirements for DNS server:
1. Standalone server (Domain controller / Member server) It is recommended to install in
Member server for load balancing.
2. Static IP address
3. Windows 2003 Server CD
To Install DNS:
Start Control PanelAdd / Remove Programs Add/Remove Windows components.

Six Important Roles of DNS:
1) Disable Recursion 2) Bind Secondary 3) Secure Cache against Pollution
4) Round robin 5) Net mast Ordering 6) Fail on Load if bad zone data.
1) Disable Recursion: If a query is passed on to the DNS server, the DNS server tries toresolve the query by searching multiple number of times. By default this option is
unchecked. If this option is checked then the DNS server tries to resolve the query
once.
2) Bind Secondary: If a query is passed on to the primary zone, if it is unable to solve it
sends the query to the secondary zone. On certain circumstances if this option is
unchecked, it doesnt even allow to create a secondary zone. By default this option is
checked.
3) Secure Cache against Pollution: When a website is visited we find multiple link sites
getting opened. By default DNS cache saves all the information where pollution is
created. And also if a website is visited enough it saves the information in C:. After
certain duration the same site is visited again, in such a case the NS makes 2 entries
where pollution is created. To solve this problem check the option.
4) Round robin: When there are multiple web servers with a single host name but
different IP addresses. The DNS server send the query to all the web serves till any
one of the server resolves the query. By default this option is checked. If the option is
unchecked sends the query to the 1st web severs only.
5) Enable Net mask ordering: If a single sever have multiple network adaptors then the
DNS sends the query to the respective NIC card only. Because by default this option is
checked. If this option is unchecked then it functions in Round robin format.
6) Fail on Load if bad zone data: If a zone has multiple records if any one of the record
is bad, it doesnt stop the functioning of the zone. Because by default this option is
unchecked. If this option is checked if any one of the zone file is bad then it disables
the entire zone itself.
To find out these six roles:
Start Programs Administrative Tools DNS
Right Click on the computer Name & go to Properties.In the options select the advance.
Displays the 6 Roles.
There are 2 types of queries in DNS
1) Recursive Query 2) Interactive Query
Recursive Query: If a client sends a query to DNS it is called as Recursive Query
Interactive Query: If a DNS sends a query to another DNS server is called as Interactive
Query
What is the Integrating DNS and Active Directory
46
8/7/2019 MCSE Classes
47/58
An Active Directory-integrated zone can be defined as an improved version of a primary DNS
zone because it can use multi-master replication and the security features of Active Directory.
The zone data of Active Directory-integrated zones are stored in Active Directory. Active
Directory-integrated zones are authoritative primary zones.
A few advantages that Active Directory-integrated zone implementations have over standard
primary zone implementations are:
Active Directory replication is faster, which means that the time needed to transfer
zone data between zones is far less.
The Active Directory replication topology is used for Active Directory replication, and
for Active Directory-integrated zone replication. There is no longer a need for DNS
replication when DNS and Active Directory are integrated.
Active Directory-integrated zones can enjoy the security features of Active Directory.
The need to manage your Active Directory domains and DNS namespaces as separate
entities is eliminated. This in turn reduces administrative overhead.
When DNS and Active Directory are integrated; the Active Directory-integrated zones
are replicated, and stored on any new domain controllers automatically.Synchronization takes place automatically when new domain controllers are deployed.
How to create an Active Directory-integrated zone
1. Click Start, Administrative Tools, and then click DNS to open the DNS console.
2. In the console tree, select the DNS server that you want to create a new DNS zone.
3. From the Action menu, click the New Zone option.
4. On the initial page of the New Zone Wizard, click Next.
5. Select the zone type that you want to create. The options are Primary, to create a new
standard primary zone; Secondary, to create a copy of the primary zone; and Stub, tocreate a copy of zone but for only the NS record, SOA record, and the glue A record.
6. Select the default selected option - Primary zone.
7. To integrate the new zone with Active Directory, and if the DNS server is a domain
controller; then you can select the Store the zone in Active Directory (available only if
DNS server is a domain controller) checkbox.
8. Click Next.
9. On the Active Directory Zone Replication Scope page, accept the default setting for
DNS replication: To all domain controllers in the Active Directory domain. Click
Next.
10. Select the Forward lookup zone option on the following page which is displayed by
the New Zone Wizard, and then click Next. 111. Enter a zone name for the new zone. Click Next. 1
12. The options that you can select on the following page pertain to dynamic updates. The
Allow only secure dynamic updates (recommended for Active Directory) option is
only available if you are using Active Directory-integrated zones. Click Next. 1
13. Click Finish to add the new zone to your DNS server.
Primary zone: This is the only zone type that can be edited or updated because the
data in the zone is the original source of the data for all domains in the zone. Updates
made to the primary zone are made by the DNS server that is authoritative for the
47

specific primary zone. You can also back up data from a primary zone to a secondary
zone.
Secondary zone: A secondary zone is a read-only copy of the zone that was copied
from the master server during zone transfer.
Active Directory-integrated zone: An Active Directory-integrated zone is a zone thatstores its zone data in Active Directory. DNS zone files are not needed. This type of
zone is an authoritative primary zone. Zone data of an Active Directory-integrated
zone is replicated during the Active Directory replication process. Active Directory-
integrated zones also enjoy the security features of Active Directory.
Stub zone: A stub zone is a new Windows Server 2003 feature. Stub zones onlycontain those resource records necessary to identify the authoritative DNS servers for
the master zone.
IIS v 6.0
Kernel Mode: Kernel Mode is a mediator between the user mode and hardware. A kernel
mode is directly interactive with hardware.
IIS v 6.0 is Kernel Mode.
IIS server is user to host Websites and FTP sites generally. IIS server in Windows 2003
comes with version 6.0. Whereas in Windows 200 IIS v. 5.0. Rather in Windows NT 4.0 IISby default is 2.0 and if install Service pack 6.0 IIS server is 4.0. IIS v 6.0 works on directly on
Kernel Mode. Where as previous versions work on the User mode. As IIS 6.0 works on
Kernel Mode it is faster to host websites.
Websites can be hosted in a windows 98 operating system also by using PWS (personal web
server). But there are lot of disadvantages compare to IIS v. 6.0 on server. IIS is installed by
default in Windows 2000 server. Whereas in 2003 IIS server is not installed by default. We
call IIS as ISM (Internet Service Manager) in Windows 2003 server. Whereas in Windows
2000 we call as IISM (Internet Information Service Manager).
Websites: We can be hosted on a IIS server by using the default port number 80. Website on
an IIS server can be configured using a different port also. There are a total 65,535 ports out
of that 1023 ports are reserved.FTP: File Transfer Protocol is specifically used for uploads and downloads. FTP site can be
configured on IIS server with a default port number 21. In Windows 2003 IIS by default the
administrator is allowed to download and denied to upload. The only one user can do both of
them, i.e. the Power User of IIS. He is calls as iuser (Internet). The administrator has to take
permission by himself in order to upload any data through the FTP site.
Once IIS server is configured the DNS server should be configured with zones. IIS is totally
integrated with DNS server.
By default in Window 200 IIS server there are 2 default websites. 1) Default website and 2)
Administrative Website.
Default website consists of help regarding IIS server. Administrative website is not available
in Windows 2003 IIS server.

There are 2 types of Routers:
2) Software Router and
3) Hardware Router.
Software Router: A software router is used to establish connectivity between 2 different
networks within a local LAN (preferred).
Hardware Router: A hardware router is used to establish connectivity between 2 different
geographical locations. Eg: WAN.Differences between a Software Router & Hardware Router:
Sl Hardware Router Software Router
1 A Hardware Router has one task to
perform i.e. Routing
A Software Router can be used to perform
multiple tasks
2 It can be configured only by
professional
It can be configured by any person with a
simple knowledge
3 There are fixed series of routers are
available in hardware routers
There are no fixed series in software routers
4 It is easily portable It is difficult for portable
5 It is costlier It is cheaper
6 It is required a third party devices
for connectivity and configuring.
Eg: Transceiver, DB9
No need to use any third party devices for
software routers.
RTL (Routing Table List):
An RTL is present within the router. RTL maintains the information of directly connected
networks to the router and also indirectly connected networks to the router.
NAT (Network Address Translator):
NAT is used to differentiate between private networks (IP address), Such that the public
network cannot access the private network but the private network can access the public
network. The NAT is implemented on the router. NAT is a layer 3 security, but with an optioncalled as Basic Firewall it functions in all the 7 layers.
192.168.1.1 192.168.2.1
DHCP Relay Agent:
DHCP Relay Agent is used to assign different network IP addresses dynamically of one
network to another. The DHCP Relay Agent takes the request from the client machine passes
through router and delivers at to the DHCP server present on the other network. Takes the IPaddresses from the DHCP server passes through the router and assign the dynamic IP address
to client.
4) Without configuring the DHCP Relay Agent on the router the DHCP server cannot
assign a dynamic IP address to a different network. Once the DHCP Relay Agent is
configured on the router no need to configure any Super Scope in the DHCP server.

Remote Access Service (RAS)
RAS is used to establish connectivity between the client and the server remotely, by using the
3rd vendor in the middle (Telephone Department).
Each and every network is by default an unsecured network. Because in an unsecured
network the data travels in a pure text format over the network. It can be hacked by
any person once the data is over the network.
In RAS concept the client machine uses the Dial-up connection to get connected to the RAS
server. In such case the client PC uses PPP (Point to Point) protocol or PPMP (Point to PointMulti-link Protocol) to establish connectivity.
PPMP protocol is used when we require huge amount of bandwidth to connect to the RAS
server. It clubs multiple lines such as ISDN, X.25 and Digi (Digital) link to get huge amount
of bandwidth. An unsecured network is also called as a physical connectivity between two
nodes. To connect the unsecured network to a secured network VPN (Virtual Private
Network) connections are used.
To have a secured network we must and should have an unsecured network first. A
secured network cannot be directly established. A secured network logical
connectivity between 2 nodes to have secured network 2 protocols is utilised. PPTP
(Point to Point Tunnelling Protocol) and L2TP (Layer 2 Tunnelling Protocol).
Initially PPTP was the industrial standard protocol for VPN connection. Later L@TP has
become the industrial standard for VPN connection. By default Microsoft Windows Server
2003 supports PPTP protocol.
A network is called as secured network because data travel in an encrypted format over the
network and will be decrypted only at the destination end.
By default 2 single unsecured networks (dial-up) a maximum of 5 VPN connections
can be established using PPTP protocol.
