Network Computing with Microsoft Operating Systems

• Microsoft Operating Systems make up the majority
  of the operating systems install base in the
  world today.
• There are a number of different types of MS
  Operating systems

(o) obsolete (eol) end of life

Networking Support in MS Operating Systems

• Since the release of Windows for Workgroups 3.11,
  MS Operating systems have supported networking as
  a core operating system feature.
• All modern Microsoft OSs support a number of
  network protocols most importantly, they
  support TCP/IP
• TCP/IP now forms the foundation for network-based
  computing environments running Microsoft
  technologies.

5
Networking Support, cont

• We can say that Microsoft OSs support three
  classes of network protocols
• Standard Protocols such as TCP/IP
• Third Party Vendor Protocols such as Novells
  IPX
• Microsoft-Specific Protocols such as Netbios
• All modern Microsoft OSs support a modular
  network kernel architecture, which allows the
  operating system to support new protocols as they
  are introduced and developed.

Network Configuration in Windows

• Windows provides a graphical interface to manage
  basic network related settings. Windows allows a
  user to
• Install drivers for NICs
• Install protocol drivers for specific Protocols
  (TCP/IP)
• Configure individual protocols (Such as IP
  Address and Network Settings)
• The starting point for Network configuration is
  Start-gtSettings-gtControl Panel-gtNetworks
• Specific verbiage may vary. For example, the
  Windows 2000 control panel applet is called
  Networking and Dial-up Connections

8
Network Properties

• The general network properties dialog box looks
  like this

NIC Installed
Protocols and Network Components Installed
9
Configuring Protocols Properties

• Protocols can be configured by highlighting a
  protocol and choosing Properties

TCP/IP Properties
Tells your computer to use DHCP
Used to specify IP address Info
Address of DNS Servers

Microsoft Networking

• There are three models that can be used for
  Windows based computers related to
  Microsoft-specific networking
• Standalone a computer that does not use any
  networking components or a computer that does not
  have any interaction or dependency on other
  computers on a network.
• Workgroup Environment a peer-to-peer
  environment that where computers are segmented
  into Workgroups, mainly used to organize and
  efficiently catalog computing resources on a
  network.
• Domain Environment a highly-advanced network
  computing infrastructure that utilizes a
  centralized user database and authentication
  methodology. Users must authenticate onto to the
  domain to get access to computing resources.
• Note A Windows computer must be one and only
  one of the above.

11
Microsoft Windows Domains

• A Windows domain environment utilizes a central
  user database, which contains user information,
  including access rights and passwords.
• Computers are configured to join the domain.
• The central user database is contained on a
  domain controller (must be a Windows NT Server or
  Windows 2000 server machine).
• When a user logs into a local PC or attempts to
  access network resources, credential information
  is passed to the domain control, which authorizes
  or denies access to a requested resource.
• The standard in corporate computing environments.
• Allows for central administration of user access
  rights and passwords.

Windows Domain and Workgroup Client Configuration
In Windows 2K, Domain and Workgroup settings can
be configured under My Computer (Rt.
