Chapter 7: Using Windows Servers



to Share Information

Sharing Files Using Windows





A
shared folder

is a connection point on a file server.




Users in a Windows Server 2003 domain are able to map these

shared folders as
network drives
.




When creating a share, consider the amount of disk space that the

people utilizing the share will need.




Do not host a shared folder on the same
volume

as the
operating

system
. If users fill the shared folder, the operating system may

halt.




You can have multiple shared folders on a volume.


Sharing Files Using Windows




You can assign
quotas

on a per
-
volume basis. This will limit the

amount of data that an individual user can store on shares.




If a volume hosts more than one share, the total amount of disk

space that the user uses across all shares on that volume must be

less than the quota.




Always provision file servers with lots of disk space. Use
RAID 1
,

5
, or
1+0

and back up regularly. Loss of a file server disk can be

catastrophic if data can’t be recovered. If you are properly

prepared, it will be only an annoyance.

Sharing Files



You can limit the maximum

number of users that can

connect to a share by editing

the share’s properties as

shown.




Permissions allows you to

restrict which users and

groups can access the share.





Offline settings allow users to

store shared files on their

laptops and have them

synchronize with the network

version when they next log on.

Shared Printers



In Windows terminology, a
printer

is the software

component of the operating system that manages printing.




A
print server

is a computer that hosts and manages more

than one printer.




A
print device

is the physical printer which outputs pages.




Printer access can be

restricted on the basis of

time of day.

Shared Printers



To restrict some users to printing at a particular time, whilst

allowing other users to print normally, create several

printers and point them at the same print device. Allow the

first group access only to the first printer, the second group

to the second printer.




A printer can point to multiple print devices. This is called a

printer pool
.




Printer pools appear to clients to be a single printer.

Windows Application Servers



Windows Server 2003 can host many types of applications,

from database servers, firewalls and proxies, through to

electronic data interchange, World Wide Web and e
-
mail

servers.




As application servers perform processing tasks for many users,

they should have lots of RAM and the best possible processor.




Consider using a multiprocessor system so that users are less

likely to overload the processor.




Generally, you should only run one major application on a

server. Microsoft has a product called Small Business Server

that bundles several important applications together on one

server. This would only be appropriate for small LANs rather

than corporate networks.

Windows E
-
Mail Servers



Windows Server 2003 ships with a simple
POP3

service. This can

provide a basic e
-
mail service to users on the LAN.




Users can connect to the POP3 service using most e
-
mail clients.




The ultimate e
-
mail server

for Windows Server 2003

is
Exchange Server 2003
.

Exchange Server 2003

includes POP3 and
IMAP4
.

Windows E
-
Mail Servers



Exchange Server 2003 also provides calendaring, public folders,

task manager, and address book service.




Another benefit of Exchange Server 2003 is
Outlook Web

Access
, a version of Outlook that can be runs in a Web browser.




Exchange Server 2003 can also perform anti
-
virus and spam

filtering functions.

Terminal Services



Uses remote desktop protocol to allow users to connect to a

server to run applications such as
Word

and
Excel
.




Clients only require a display, keyboard, a mouse, and the

terminal services client software.




Processing occurs on the server, which means that older

computers can be used to access the latest applications.




Instead of spending tens of thousands of dollars upgrading

desktop workstations every few years, organizations can

spend less money upgrading their centralized terminal

servers.




Terminal server client software runs on multiple platforms.

Internet Information Services



IIS is included with Windows Server 2003, but not installed

by default.




Prior versions of Windows had these services installed by

default. Administrators were often unaware of this and only

found out once their server had been compromised.




IIS includes the following servers:



W
orld
W
ide
W
eb (WWW)


F
ile
T
ransfer
P
rotocol (FTP)


N
etwork
N
ews
T
ransport
P
rotocol (NNTP)


S
imple
M
ail
T
ransport
P
rotocol (SMTP)




IIS WWW Server



Most people use IIS for its Web server component.




IIS Web server is managed through Internet Information Services

Manager console.




IIS supports multiple Web sites. Sites must be differentiated by

either
FQDN
,
IP address
, or
TCP port

number.

IIS WWW Server



Access to the Web server can be restricted on the basis of IP

address, domain name, user account credentials, or digital

certificate.




You can restrict the number of users who access a Web site

concurrently.




The amount of bandwidth a Web site uses can be limited so that

your organization’s Internet link isn’t flooded if a page is posted

to a popular Web site and you get an influx of visitors.




You can configure IIS to automatically restart Web sites that have

failed.

Other IIS Services



SMTP server supports the sending of e
-
mail. Can be used in

conjunction with the POP3 service or Exchange Server 2003.




NNTP server supports Usenet, a text
-
based messaging system that

was very popular in the 1980s and 1990s.




FTP server can be used to transfer files to and from server.




FTP is a 30
-
year
-
old protocol used for transferring files. It is fast

because it has low overhead.




IIS also support file transfer with WebDAV technology more

securely on the WWW server.




Benefits of WebDAV: Authentication and transfers can be

encrypted. Disadvantages: Slower than FTP.

Routing and Remote Access



RRAS

service can be configured to allow users to access the

network via modem or VPN through the Internet.




VPN

(virtual private network) is an
encrypted

connection

through the Internet.



Users connect to

their
ISP

normally and

then initiate a VPN

connection to the

Windows Server 2003

RRAS server. Once

established, they have

normal LAN access.




Managed via the RRAS

console.

Summary



When configuring shared files, be sure not to place the share

on the operating system volume.




Implement quotas to ensure that the share does not run out of

space.




A printer is software that points to the hardware print device.




An application server needs the best RAM and processor

possible to cope with the load of many people using it.


Summary



Windows Server 2003 ships with a basic POP3 client. The

most extensive e
-
mail server solution for Windows is

Exchange Server 2003.




Internet Information Services includes WWW, NNTP,

SMTP, and FTP servers.




You can restrict access to the WWW server on the basis of IP

address, domain name, username, and digital certificate.




You can configure Routing and Remote Access to provide

VPN and dial
-
up access to your organization’s LAN.

Discussion Questions



What methods can you use to limit access to the IIS World

Wide Web Server?




What benefits are there of using VPN rather than dial
-
up

connections to your organization’s LAN?




What mail protocols are supported by a native Windows

Server 2003 installation?




What should you take into account when setting up a file

share?




What are the differences between a printer, a print device, a

print server, and a printer pool?
