What is a Microsoft Internet Information Server?

• It is Microsofts Web server that allows for the
  management of Web-related applications, files and
  data.

4
What is a Web Server?

• A Web server is a specialized program that uses
  the client/server model and the World Wide Web's
  Hypertext Transfer Protocol (HTTP) to present
  files in the form of Web pages to the users.
• Source www.whatis.com

5
Example of the Use of a Web Server

• When we type in www.calstatela.edu/ats/cbt.htm,
  we are directed to the web server
  with the domain name www.calstatela.edu.
• The web server then finds the ats directory and
  the cbt.htm file. It then forwards the file
  directly back to us.

6
Uses of the Internet Information Server (Examples)

• Corporate workgroups using intranets
• Corporate partners using extranets
• Customers logging on to a Web site

7
Where can you find the Microsoft Internet
Information Server?

• The Internet Information Server is found in the
  Microsoft Option Packs
• All NT Servers shipped after January 1998 come
  with Internet Information Sever

• The minimum installation program is designed to
  conserve disk space on your system.
• The typical installation installs all the
  components of IIS included in the minimum
  installation. In addition, it installs the rest
  of the optional IIS components. Included in the
  typical installation is the FTP service, the
  Internet Service Manager (HTML), and help on
  server administration, content management, and
  content development.
• The custom installation allows you to choose
  which IIS components you want on the computer,
  apart from the components that are required and
  selected by default.
• Lets choose the Custom installation, which
  allows you to select any combination of
  components in addition to the IIS component that
  is required to run the IIS server.

• If you are using IIS on an intranet, you can copy
  the unattend.txt file from the Option Pack CD to
  a folder on the local computer (The unattend.txt
  file is located on the CD in the
  CPU_Type/inetsrv/directory, where CPU_Type is the
  processor on the computer where IIS will be
  installed.) This file allows you to perform
  unattended installations from that folder. This
  is useful for performing installations without
  having to remain at the computer and step through
  the installation options.
•  To start the unattended setup, you either place
  the CD in the CD drive, or make a network
  connection to the CD drive containing the Option
  Pack CD. You then copy unattend.txt to your local
  hard disk and make any necessary changes to
  install the appropriate components.
•  At a command prompt, you change to the folder on
  the CD containing setup.exe, then enter the
  following path setup/ultfull path to
  Unattend.txtgt. For example, if the file located
  in the temp directory on the C drive, you type
  setup/uc\temp\unattend.exe

43
TROUBLESHOOTING
TCP/IP
44
Presentation Objectives

• Identify some of the problems which may arise in
  a network that uses TCP/IP as its communication
  protocol
• Explain the utilities that are available for
  troubleshooting TCP/IP

45
TCP/IP Problems

• Configuration of the local computer
• Connecting to other hosts on the network
• Routing problems
• Naming resolution errors
• Source and destination hosts are trying to
  communicate using different protocols

46
Tools that come with Windows NT

• Microsoft SNMP Service
• Event Viewer
• Performance Moniter
• Registry Editor
• Network Monitor, Agent, and Tools

47
Utilities used for troubleshooting TCP/IP

• IPConfig
• Ping
• Hostname
• Nbtstat
• ARP

• Tracert
• Nslookup
• Netstat
• Route

48
IPConfg

• Display current TCP/IP network configuration
  values, and update or release TCP/IP network
  configuration values.
• Display IP address, subnet mask, and WINS and DNS
  configuration.

52
Ping

• Verify whether TCP/IP is configured correctly and
  that a remote TCP/IP system is available.
• Ensure that a host computer you are trying to
  reach is actually operating.
• Used with a host that is operating to see how
  long it takes to get a response back.

53

• Ping sends an ICMP echo request to a target host
  name or IP address.

54
If there is an error message using your own IP
address, view the configuration to check and
correct it.
55
Nbtstat

• Useful tool for solving NetBios name resolution
  problems
• Switch to display the names that were registered
  locally on the system

56
Nbtstat
57
-a Lists the remote computer's name table given
its host name. -A Lists the remote computer's
name table given its IP address specified in
dotted decimal notation. -c Lists the contents of
the NetBIOS name cache, with the IP address of
each name. -n Lists local NetBIOS names. In this
listing, "Registered" indicates that the name has
been registered on this network node, either by
b-node broadcast or by a WINS server.
58
-R Reloads the LMHOSTS file after purging all
names from the NetBIOS name cache. -r Lists name
resolution statistics for Windows networking. On
a computer configured to use WINS, this option
returns the number of names resolved and
registered broadcast or WINS. -S Displays both
workstation and server sessions, listing the
remote hosts by IP address only. -s Displays both
workstation and server sessions. It attempts to
convert the remote host IP address to a name
using the HOSTS file.
59
Nbtstat

• When adding more than 25 dialout devices under
  Windows NT 4.0 RAS, the NBTSTAT command will
  return the following message
• Unable to access NBT driver Unknown Error
• This problem is because NBTSTAT is not reading
  the entire contents of a registry key.

60
ARP

• ARP (Address Resolution Protocol) is a protocol
  for mapping an Internet Protocol address (IP
  Address) to a physical machine address that is
  recognized in the local network.
• The most common level of IP in use today, an
  address is 32 bits long.

61
How ARP Works

• When an incoming packet destined for a host
  machine on a particular local area network
  arrives at a gateway, the gateway asks the ARP
  program to find a physical host or MAC address
  that matches the IP address.

62
Route

• The route table controls any routing decisions
  made by the hosts on a network
• You can display the route table using the Route
  Print command.

63
Route
64
Tracert

• Examine the route between two nodes on a network
• Determines the route by sending the first echo
  packet with a TTL of 1 and incrementing the TTL
  by 1 on each subsequent transmission until the
  target responds or the maximum TTL is reached.

65
Tracert
66
Netstat

• Displays protocol statistics and current TCP/IP
  network connections.
• Syntax netstat -a -ens -p protocol
  -r interval

Nslookup

• Lets an Internet server administrator or user
  enter a host name and find out the corresponding
  Internet Address. It will also do reverse name
  lookup and find the host name for an IP address
  you specify.

71
Nslookup

• For example, if you entered "whatis.com", you
  would receive as a response our IP address, which
  happens to be
• 199.45.146.176
• Or if you entered "199.45.146.176", it would
  return "whatis.com".

Internet Information Server - Web Applications

• Group 4

73
Introduction

• Internet Information Server can be used for
  interactive applications and scripts for your
  website.
• IIS can be used for CGI Scripts and ISAPI
  Applications.
• Using IIS with ASP pages on a server.

74
Methods

• CGI(Common Gateway Interface)
• ISAPI(Internet Server Application Program
  Interface)
• ASP(Active Server Page) Applications
• SSI(Server Side Includes)

75
CGI
76
CGI

• What is CGI?

77
CGI
78
CGI

• CGI script conforms to CGI standards.
• Scripts or programs can be written in any
  language for applications to be executed on a
  system.
• These languages can be C, PERL, Visual Basic,
  and NT Batch Files.
• Programs such as VB and C need to be compiled
  in order to work. Scripts do not need to be
  compiled and are much more portable.

79
CGI Security Issues

• There are several security issues in regards to
  CGI.
• Intruders and hackers can manipulate CGI script
  to access sensitive information such as passwords
  and registry files.
• They can also use CGI script to run system
  commands. This risk can be reduced by having
  experts write the scripts and keeping them in one
  single directory with only an administrator
  access.

80
CGI - Requirements

• To write CGI Scripts a working knowledge of HTML
  and HTTP protocol is needed.

81
ISAPI

• What is ISAPI(Internet Server Application Program
  Interface)?

82
ISAPI

• Applications that use ISAPI have executable code
  that reside in NT DLL(Dynamic Link Library).
• There two areas of development are applications
  and filters.
• ISAPI applications are known as Internet Server
  Applications(ISAs)

83
ISAPI How It Works
84
ISAPI and CGI
85
Active Server Pages(ASPs)

• Active Server Pages are a scripting environment
  that overcome the limitations of CGI.
• With ASP you can combine HTML, scripts, and text
  on web pages.
• The built-in Active X components can be used to
  perform dynamic tasks, such as connecting to a
  database or performing calculations.

86
ASP

• ASP eliminates the need to learn a full
  programming language or compile programs
  separately.
• Any scripting language that follows the ActiveX
  scriting standard such as Vbscript or Javascript.
• To use other languages such as PERL, Python, or
  REXX you need a separate scripting engine from a
  third party developer.

87
ASP Properties
88
ASP Security

• ASP offers the most security of the three methods.

89
ASP Advantages

• ASP applications are easy to modify and develop.
• An ASP file is simply a text file that can
  contain HTML tags and embedded script commands.
• ASP uses ActiveX Control which are essential to
  dynamic web pages.

90
Summary

• Internet Information Server can be extended to
  use CGI, ISAPI, and ASP for web applications.
• CGI is the most common but ISAPI, and ASP are
  also used.
• ASP offers several advantages over CGI in terms
  of security, capabilities, and browser
  compatibility.
• Internet Service Manager can be used to specify a
  starting point directory and to configure your
  application.
