Static Addressing 1 Dynamic Addressing and DHCP

It is beyond the scope of this book to explain in detail the stage of how the software must be configured, since there are plenty of protocols and operational systems. It is, however, necessary to show the basic points how to set up a connection with the Windows systems under the TCP/IP protocol.

First, network interface cards are physically established and the necessary drivers are installed. Therefore, on the desktop a folder, My Network Places, should appear.

Go to folder "network and dial-up connections", click the right button of the mouse on "My Network Places" and select Properties.

It is further necessary to choose the folder, "Local area connection", and open the appropriate window by clicking the right mouse button on “Properties”. "The Client for Microsoft Networks" will be established automatically. The folder, "File and printing sharing for Microsoft Networks", is used to work through a network medium and for access to the Internet, it is not necessary.

Depending on the particular installation circumstances, the necessary service or protocol is easy to add or to remove with the use of the appropriate buttons.

Some adjustment requires "Internet Protocol (TCP/IP)". In the appropriate fields, it is necessary to register in an obvious kind the IP-address of the computer for example address 192.168.23.117 and mask 255.255.255.0.

To register the address of a gateway and DNS for a simple network there is no necessity to assign specific numbers.

Serviceability of the configured network is convenient for checking by a ping command. For this purpose from a command line type the line “ping 192.168.23.118” (address with which it is necessary to communicate) and hit enter. If the answer is of type "the Reply from 192.168.23.118: bytes=32 time<10ms TTL=128 " turns out, all is made normally, and at the IP level network works. If the answer Request timed out", something is made not correctly, and it is necessary to search for the reason of the malfunction.
