Adjusting TCP / IP network settings

TCP / IP settings can be defined in two ways:

• Dynamically (automatically) - through the DHCP Server service
• Static - direct admission on the basis of the records in the DNS server table

DHCP (Dynamic Host Configuration Protocol) is a computer service that automatically assigns TCP / IP settings. They are not changing the existing computer name and the group. Administrator must determine the labeling scheme and the computer belonging to the group to avoid any conflicts in the view /Network Neighborhood/ misrecognition and neighbors. This is a useful feature to configure the laptops, which each time a new connection to the network to get a new IP address in the range assigned to the DHCP service. But access to shared resources, it is difficult because they do not go directly over known IP addresses. The names of these computers are not located in the DNS server table.

Static addresses are entered manually into the computer on the basis of the DNS (Domain Name System) Server service, or on the basis of entries in the table by a network administrator manually configured. The following is based on the method of entering the DNS records.

Figure* 4.3.15 Enter the IP address and status protocol. ( + / - )

A network administrator assigns the computer's IP address and its network mask, and from this presentation can be concluded that the computer is a member of a private network C-Class, which can be read in more detail in the section on the Internet. So users of network resources can not write his address that comes to mind. Private IP address means that the network is protected by a firewall. Folders /Bindings/ describes the protocols used in the configuration and can be switched off unnecessary.

With this data, the computer is recognizable in the network, but still does not know where to leave the network, and where there is a server that is registered in the DNS its content and where the account user. The following Figure shows the parameters that need to be entered for this purpose.

Figure* 4.3.16 Type 'Exit' (Gateway) and DNS. ( + / - )

To exit the network should be in the folder /Gateway/ enter the IP address of the device that connects the entire network with a superior network equipment. Pressing the field |Add| adds the entered address in view |Installed gateways|. If there is another possible way ga also be added to the list. In a similar way, a pen pal's address DNS server, which can also be more. In the picture shown is one enrolled and one who has entered by pressing the field |Add|. Be sure to fill two more columns /Host:/ (host name) and /Domain:/ (domain like 'informatics.buzdo.com', 'krs.hr', 'bug.hr' and the like), of course, based on data gave the network administrator. Although the examples in this Chapter Workgroup=Spalato and Domain=spalato.hr, one with another and have nothing in common. The first is to display data network members within their network and /Network Neighborhood/ shown all groups and click on the group icon will display the members of that group, and other information belonging environment that provides Internet service. In Windows XP operating system settings described enrolled in a unified form to Figure 4.4.32, as well as the form in Figure 4.5.93c for Windows 7 operating system.

How to check that all is well written and if it works? Very simple. Selects the menu {START}-{Programs} icon MS-DOS Prompt. When you open a DOS window and enter the command ipconfig /all to get a complete listing of network settings. It is not superfluous to note once again that the two computers (a host) on the network may not have the same name or IP address. When the computer is turned on only one will notice anything. Conflict is inevitable when the network includes another computer where the name or IP address is the same as that already included one computer. On screen both computers 'jump' will quickly alert window with the conflict. Different domains or group resolves the conflict.

Example I

Printout of command ipconfig /all at Windows 98SE operating system is connected to the network via a cable modem.

 c:\WINDOWS>ipconfig /all

With regard to the above, it is clear that the network card can be configured to operate in one network and can not be a 'member' of a few networks regardless of the protocol used.

For a similar print in Windows 98 and Windows ME to use the command winipcfg. Of gold command line. There's more. Read the instructions and learn. Useful. Do you have it? Google?
