Damage or hardware errors that often happens is that the Network Interface Card (network card), pengkabel and connectors. Damage or fault on the network is often caused by the connection (relationship) is not well between components and component malfunction due to dead or damaged. a) Network Interface Card (network card) Physically to recognize that the network card has been atkif or inactive can be seen on the indicator light located in the network card when the computer is on and the network card has been associated with a network cable then the indicator light must be lit. If not lit means that there are problems or damage to the network card. In the software to know that the network card has been working or active can be viewed at:
(1) Click Start> Settings> click Control Panel (2) Select double-click the system icon menu select Device Manager
There can be seen that the network card is already known or not. When you are known then the computer's network card can work or actively. b) Wiring and Connectors Selection of communications media using cable as a liaison between computers is an ideal medium in comparison with other media such as the RF (radio frequency), IR (Infra Red) or telephone line because it is cheap, easy and have a fairly high data rates. But errors in the wiring rules, the quality of the cable itself, and the layout or topology of the network often interfere with the cable network system.

Damage or Software error
The problems that often arise on the part of this software in general can be grouped by:a) Error setting network configurationConfiguration setting errors often occur on the network card that uses the ISA model because we have to determine:(1) Video port I / O(2) Number interrupt(3) Direct Memory Access Request line(4) Buffer Memory AddressUnlike the model card ISA network card that uses PCI model does not need to set as it automatically becomes available.b) Protocol error usedThis often happens on the network card that uses the ISA slot because the determination must be done manually. If we use the protocol model of the PCI network card that rarely happens when we have installed drivers correctly.c) Errors of IP addressing.Every computer on a network is the identification of a unique address, so it is not allowed to have the same address. IP addresses within the same network is not allowed because it is an identity for each computer in the network for data communication, in case the same address then the two computers can not access the network due to the seizure of the address number.d) Error Identification Client and server computersDetermination of server computers and client computers must be clear to client server networks, in contrast to the peer to peer network there is no determination of client and server.e) Error Service Network (file and print sharing)Service network (file and print sharing) could be due to an inactive file and print sharing which we reach is not active or are we not doing file and print sharing.f) Security System ErrorPassword entry errors when we enter into the network so that we can not enter the network due to security errors (password).g) Damage to the program files, so it needs to be updated.Program files that cause damage to the operating system can not run or cause the network card can not work (not active).To be able to make improvements in the software errors can be done by resetting the software in accordance with the provisions in the network. Here are some cases that is often caused by networking operating systems:- Unable to Login in the networkCan not enter the network means the client can not access the network as a whole.- Unable to find other computers on the network neighborhood lists. If the hardware and software is no problem to do restart the computer to store all the data that we have an update to the operating system.- Can not share files or printers.Sharing files or printers is open access to other computers to access or view our data. Unable to share files or printers can be due to the data or the printer is not in sharing. to be able to do the sharing can be done by right clicking the share.- Unable to install network adapter.This case is usually caused by sorfware network card that does not fit between the driver with a network card or network card installation is not perfect on the mainboard, so the computer can not recognize the network card.Things to do with the checks on whether the network card is properly inserted or the network card was installed with default drivers.- Other computers can not be entered into our computer.Other computers that can not be entered into our computer when we can get the computer to another computer because we have not made data sharing or printer sharing.These cases can be resolved if no errors occur when software on the network card settings. Setting the network card is very important to the relationship between computers, if something goes wrong then cause the computer can not be connected in a network. Error checking should be done one by one carefully in accordance with the conditions set on the network include IP numbering and subnetmask on the protocol used, the name Workgroupnya and so on.
