IIS and PWS

What is IIS and PWS? Microsoft Internet Information Server (IIS) and Peer Web Services (PWS) enable Windows NT servers with the ability to provide Hypertext Web pages and interactive Web client/server applications for the internet and/or the private intranets. IIS and PWS use HTTP, Gopher services and FTP. Typically, you install IIS on an NT 4.0 server and PWS on an NT 4.0 workstation support. IIS is designed to support high volume traffic while PWS is better used to support Web services for small installations.

What is an Intranet? “An intranet is a network, internal to an organization, that uses Internet technology, such as the HTTP servers and Web browser services, to improve internal communications, information publishing, or the application development process.” Supporting MS Windows NT 4.0 Core Technologies. Microsoft Education and Certification.

Dynamic Host Configuration Protocal (DHCP) Enable a DHCP server, such as an NT server, to automatically assign IP addresses to client computers including remote ones

Windows Internet Naming Service (WINS) WINS provides automatic resolution of logical computer names into IP addresses Example: to

IP Address Class Class,1st octet, network id, host id, available network, available hosts on each network A, 0-127, fff, sss.ttt.lll,126, B, , fff.sss, ttt.lll, 16384, C, , fff.sss.ttt, lll, , in first octet for loopback testing, ( ) return the message to sender in the first octet for multicasting, broadcasting to many hosts on the same network in the first octet for experimental purposes

Subnets 32 bits in one IP address Two parts –Most significant bits (MSB) identifies a specific network 0 for the first bit for class A 10 for the first two bits for class B 110 for the first three bits for class c –The rest bits identify a host on the network Subnet breaks down the hosts into smaller groups

Subnets Class A –[0xxxxxxxx] [xxxxxxxx xxxxxxxx xxxxxxxx] –[network] [host] –[0xxxxxxxx] [xxxxxxxx xxxxxxxx] [xxxxxxxx] –[network] [subnet] [host] Class B –[10xxxxxx xxxxxxxx] [ xxxxxxxx xxxxxxxx] –[network] [host] –[10xxxxxx xxxxxxxx] [xxxxxxxx] [xxxxxxxx] –[network] [subnet] [host]

Subnets Class C –[110xxxxx xxxxxxxx xxxxxxxx] [xxxxxxxx] –[network] [host] –[110xxxxx xxxxxxxx xxxxxxxx] [x] [xxxxxxx] –[network] [subnet] [host]

Subnet Mask Subnet mask determines the number of bits used for the subnet and host portions of the IP address 32-bit value: 1-bits for the network and subnet portions and 0-bits for the host portion Reserved numbers in a subnet –The first number is for the entire network –The second number is for the default router –The last number is for the broadcast address for braodcasting to each machine

Example for Class C Subnet –No. of mask bits: 0 –Subnet mask –No. of subnets: 1 –No. of hosts: 253 –Network number: –Router address: –Broadcast address:

Example for Class C Subnet –No. of mask bits: 1 –Subnet mask –No. of subnets: 2 –No. of hosts: 125 –Network number for subnet 1: –Router address for subnet 1: –Broadcast address for subnet 1: –Network number for subnet 2: –Router address for subnet 1: –Broadcast address for subnet 1:

Example for Class C Subnet –No. of mask bits: 2 –Subnet mask –No. of subnets: 4 –No. of hosts: 61

NIC Address Unique Hardware address or MAC address A six-byte vendor number and a six-byte network number Router has one NIC for each network Routing address: IP address and Hardware address IP address stay, hardware address change from one router to another

Name Resolution Domain name and IP Domain Naming System (DNS) name server is a distributed database system to enable a computer to look up a computer name and resolve the name to an IP address Windows Internet Naming Service (WINS) provide a dynamic database for managing name resolution When DHCP assigns network addresses, WINS automatically updates the name database to add DHCP IP address assignments

How to Build an Intranet? Install TCP/IP on the client computer(s) Install TCP/IP on the NT 4.0 Server Install and configure DHCP and WINS services (optional but recommended) Install and configure IIS Post Intranet material

How to Install TCP/IP and DHCP 1. Select the Network program from the Control Panel 2. Select the Protocols tab and click Add

3. Select the TCP/IP protocol and click OK 4. Click Yes to install the DHCP server

5. The required files are in D:\NT40SRV\i386 directory

How to Configure TCP/IP 6. Go to TCP/IP properties and specify the IP address and Subnet mask 7. Select the DHCP Relay tab and set the server’s IP address as the DHCP Relay 8. Add the DHCP Relay agent service 9. Save your settings

How to Configure DHCP 1. Select DHCP manager from the Administrative Tools

2. In the DHCP server create a scope

How to Install WINS 1. Select the Network program from the Control Panel 2. Select the Services tab and click Add 3. Select Windows Internet Name Service 4. The required files are in D:\NT40SRV\i386 directory

How to Install IIS 1. Select the Network program from the Control Panel 2. Select the Services tab and click Add 3. Select Microsoft Internet Information Server The required files are in D:\NT40SRV\i386 directory

5. Select all options and install in the default directories.

How to Configure IIS Use the Microsoft Internet Service Manager (ISM) to configure and monitor the Intranet services running on any computer in your network. ISM enables management of multiple servers from one computer including: Connect to servers and view server properties Start, stop, or pause a service Select which services to display Configure service properties (WWW service, Gopher service, FTP service)
