Microsoft Windows 2003 Server
Client/Server Environment

Many client computers connect to a server.
Client Computer Responsibilities

Users can use these computers to run
applications.



Microsoft Word
Microsoft Excel
Users can access other resources



Internet
Printers
Files
Server Responsibilities

Provide services for the client computers.




Share printers
Share files
Share internet
Provide networking services

DHCP
DNS
Web Server
Email Server
Security

Security is very important in computer
networks.

Each user has their own:



Username
Password
To use the computer, the user must remember
their password.
Server Validation



User types in their username and password
in the client computer.
Client computer sends the information to the
server.
Server checks if the username and password
are valid.
Login
Username
OK

Server
What is a Domain?

A group of computers and servers using
client/server architecture.
What is a Workgroup?

A group of computers using peer to peer
architecture.
Domain Name Server


Every domain must have a DNS server.
The DNS server contains a list of


IP Addresses
Computer names
Why use computer names?



IP addresses are difficult to remember
Computer names are easier to remember.
Can you remember www.google.com or
216.239.41.99?
Forward Lookup Queries

Request the IP address for a computer name
www.google.com
216.239.41.99
Client

DNS Server
How to find an IP address for a computer:

Run nslookup.exe with the computer (host) name.
IP Addresses

Computers can only use IP addresses to
communicate with each other.

Users want to use computer names to access
other computers.

DNS lets us convert computer names to IP
addresses.
Windows Internet Naming Server



WINS is Microsoft’s version of DNS.
Server stores a list of computer names and
IP addresses.
WINS server only keeps the IP addresses for
computers in the local area network.
Domain Controller

Domain Controller is a server that contains
the following:




Usernames
Passwords
Computers
When you log in to a client, the client
connects to the domain controller to validate
the password.
Dynamic Host Control Protocol




Each computer must have a unique IP
address.
You may type in a unique IP on each
computer, or you may install a DHCP server.
The DHCP server contains a list of available
IP addresses.
When a computer connects to the network,
the DHCP server will give it an IP address.
DHCP Protocol
IP address???
192.168.0.101
Client



DHCP Server
The client requests an IP address from the
DHCP server.
The DHCP server responds with the IP
address.
Note: DHCP can run on your domain
controller, or on a different server.
Setting up the Network

Go to the network properties for your server.

Put in the following values for IP protocol:



IP Address: 192.168.0.1
Subnet Mask: 255.255.255.0
DNS Server: 192.168.0.1
Setting up the Server: Services

Access the Manage Your Server program


Starts automatically
Also access through Administrative Tools
Setting up the Server: Services(cont.)


Add a role to your server:
You can see the different services:





DHCP
Domain Controller
DNS Server
WINS Server
Choose a service and install it
Installing DHCP Service


Choose the DHCP Server and click next
To use the DHCP service, you need to create
a scope. Call it what you want.
DHCP Scope



You need to put in a
start IP address and
finish IP address for the
scope.
These addresses
should be in the same
network as your server
(192.168.0.XXX).
IP Addresses will be
given from this range.
DHCP Exclusions


You may add exclusions as well.
IP addresses in the exclusions screen will not
be given out.
Lease Duration


Lease duration tells the computer how long
the IP is valid for.
After the duration is finished, the client will
request another IP address.
DHCP: Additional Options

You may also specify extra values in the
server.

The client will download these settings from
the server with the IP address.
DHCP Settings: Gateway


The gateway is the server that connects to
other networks (i.e. the Internet).
The IP address is normally the first IP in the
network (192.168.0.1)
Domain Name and DNS


Choose a name for your domain and put it in
parent domain. (i.e. TIHE.ORG)
Also, put in the IP address for your server for
the DNS server.
WINS Server

Put in the IP address of your server for the
WINS server as well.

When you are finished, activate the scope.
Domain Controller


Now we will install the Domain Controller,
select this service from the Manage Server.
We want to create a new domain.
Domain Forest


In Windows Server, you can connect your
domain to an existing domain structure, or
you can start from scratch.
We will create a new forest for our domain.
DNS


DNS is integrated with the Domain Controller.
Select the second option – Have the
computer install DNS for you.
Domain Name

Now you need to select a domain name. It
should be the same name you used in the
DHCP (i.e. TIHE.ORG)
NetBIOS Domain Name

The computer will choose a netbios name for
your domain. Click next.
Database and Log Folders

The computer will select a path for this entry.
Click next.
Shared System Volume

The computer will select a path for this entry.
Click next.
Permissions

You will probably only be using W2K servers,
so select the second option.
Restore Mode Password

Choose the same password that you used to
make the server.
Running Active Directory


Active Directory allows you to manage the
users and computers in your domain.
Open Active Directory Users and Computers
from Administrative Tools
Organizational Units


Before we can create a new user, we need to
put that user in an Org Unit.
Organizational Units group similar users
together like a folder.

Staff, Students
Creating a New User

Now that you have an Org Unit, you may
create a user inside.
New User Dialog

Insert information for your user, following the
dialogs.
Password Problem

Depending on your settings, you might get an
error message when creating the user

This message will appear if your domain
requires complex passwords



Letters
Numbers
Special Characters (i.e. !)
Disabling Complex Passwords


Open your domain security policy
Disable the password requirement
Update Your Policy

Run gpupdate
Additional Settings: Group Policy


You can make a policy for each Org Unit
Go to the properties and make a new Group
Policy
Editing the Group Policy

Most of the settings you want to change are
under the User section under Administrative
Templates.

Explore these settings.
File Sharing


Windows Server makes it easy to share files. All we
need to do is turn on the File Sharing Role for our
server, then add the folders we want to share.
Go to “Administrative Tools” and then “Configure Your
Server Wizard”. You will then select the File Server
Role
There
is not much to configure
your File Server, but it will ask
you if you want to share a
folder with the File Sharing
Wizard.
File Sharing



The File Sharing wizard allows you first to select the
folder you want to share. This folder will be a place
on your hard drive that you would like others to see
The next screen will ask the Share Name that others
will see over the network. Note: The Share Name
does not need to be the same as the folder name.
The share name is the name that the folder will have
over a network
Finally, it will ask you to select permissions that
apply to your folder. Administrator has full access,
others have read-only will be good for just sharing
files.
Home Drives




Now that we can share folders and files, it is
useful if each user can have a folder where
they can save files on to the server.
That way, if they use another computer, they
can still have access to their files.
This is usually called a “Home Drive” and we
will map a network drive to a shared folder
Let’s make a shared folder where people can
save data now…
Home Drives
Home Drives




To enable this feature, we
will go to Active Directory
Users and Computers and
select a user.
Right click on the user and
go to properties.
In properties go to Profile
In the “Home Folder” box,
select Connect, choose a
Drive and then put in the
path to the folder from the
network
Network Paths

Your computer, remember, is accessible over
the network if you type “\\” before the
computer name and then type the folder


Example: \\tihe1\HomeFolder
In the Connect box, put the network path
(sometimes called the UNC) to the folder that
will save the user drives.
Home Folders



After you press OK, a folder for that user
should have been created in the shared
folder that you made.
If you look at the security permissions for that
folder, you should also notice that only
administrator and that user have access.
Now if you need to make another user, you
can copy from that user (Right click, go to
Copy) and the Home Folders settings will be
copied over.
Joining a Domain




Now that you have a server set up, you need clients
to use the server.
For Windows XP, you must have the Professional
version in order to use a domain. Windows 98, ME
and 2000 can all connect to a domain without any
other changes.
In order to join a domain, we must go to our client
computers, go to the place where we joined a
workgroup
Now we will select the domain option and type in the
full name of our domain (Ex. tihe.org)
Joining a Domain



The next screen will ask for a username and
password. This is asking for the administrator
username and password from the server you
setup
It will then welcome you to the domain.
The next step is to change the IP settings to
obtain the IP address automatically. This will
allow the client to use the DHCP server you
have made
Joining a Domain




Now you should restart your client.
When the computer restarts you will be able
to use the usernames and passwords you
have made with the Active Directory
This is because your are now using a
Client/Server relationship where the server
provides a service to the client.
Windows calls this a Domain
