4
Default Windows NT Network Protocols and their
comparison

• NeBEUI
• TCP/IP
• NWLink (IPX/SPX)

5
Advantage of NetBEUI

• Small memory overhead.
• Very fast on small network.
• Error protection.
• Self configuration and self-tuning

6
Disadvantage of NetBEUI

• It is not a routable protocol.
• Very little support for cross platform
  application.
• Very few troubleshooting tools.

7
Advantage of TCP/IP

• The most flexible transport protocols. Excellent
  cross-platform support.
• Direct access to Internet.
• Strong support for routing.
• SNMP support..
• DHCP support.
• WINS support.

8
Disadvantage of TCP/IP

• Difficult to administer correctly and difficult
  to setup.
• Slower than NWLink(IPX/IPX) and NetBEUI.
• High overhead
• Centralized TCP/IP domain assignment requires
  registration effort and cost.

9
Advantage of NWLink

• Easy to setup.
• Support routing between networks.
• Faster than TCP/IP.
• Allows easy connection to installed NetWare
  servers and client.

10
Disadvantage of NWLink

• Does not have an effective central addressing
  scheme to prevent two network from using the same
  address number.
• Shower than NetBEUI.
• Doesn't support SNMP( Simple Network Management
  Protocol).

11
NT Networking Services

• Browser Service.
• DHCP(Dynamic Host Configuration Protocol).
• WINS(Windows Internet Name Service).
• DNS( Domain Name Service).

12
The Function of Browser Service

• Identify and list the available network
  resources, in order for these resources to be
  used efficiently by sharing, that is an advantage
  of networked computer system.
• By assigning the browser role to specific
  computers, lowers the mount of network traffic,
  also frees the CPU time that each computer need
  to create a network resource list.

13
The Function of DHCP

• Centralize and manages the allocation of TCP/IP
  configuration information by automatically
  assigning IP address to computers
• Automatically configure subnet mask to identify
  destination network ID. If it is not the same as
  your network ID, then forward message to gateway.
  
• Automatically configure your gateway ID address.
• Automatically set DNS address.

14
The Function of WINS

• Be used to register NetBIOS computer network
  names and resolve them to IP address.
• Sample What is the best way to decrease
  TCP/IP-based network broadcast traffic?
• If without WINS, each computer on network has to
  send a broadcast message to other computer on the
  network. Install WINS, provide computer name to
  IP address resolution that reduces the broadcast
  traffic.

15
The Function of DNS

• Resolve domain name to IP address.
• Sample
• Need to provide an Internet name to IP address
  translation on TCP/IP based network, what service
  need to install on Windows NT Server computer?
• Administrator can use DNS to manage domain and
  computer names.

16
Network Monitor

• Monitor the data that is sent over network.
• Collects, filters, and analyzes frames or
  packets.
• Each frame contain
• Source address.
• Destination address.
• Headers from each protocol used to send the
  frame.
• Data.

17
Information captured by Network Monitor

• Bar graphs
• Provide information on real-time network activity
• Session statistics.
• Show the conversations that are taking place on
  the network. Real time and cumulative.
• Station statistics
• Cumulative information on network conversation.

18
Summary Windows NT Network Features.

• Flexible Protocol Support
• Multiple Network Service Support.
• Multiple tasks to monitor network traffic .
