How to Troubleshoot LAN ? - Troubleshoot Lan

Post by Jawad Ahmad Riaz

The process of identifying and discarding the problems of network is known as trouble shooting LAN. The careful monitoring of nay system at reasonable intervals is really helpful in eliminating the problems of any network. Design and plan the network at regular basis to improve the efficiency of the network.

Problems to Deal with

A network management computer can significantly help in monitoring a LAN network. Protocol analyzers are used to troubleshoot the LAN mostly. LAN TCP/IP trouble shooting is often very complex. The process of trouble shooting has many states. It starts with finding the duplicate network address residing in a network, improper network configurations and applications, network devices which are not optimized for further improvement, downsides of service, the problems to deal with cables, slipup of LAN cards , viruses, spy ware attacks, firewall up gradation, other security concerns, overloading in network and proxy problems.

Process of Trouble Shooting

 It is easy for a network administrative to deal with the problem of LAN settings only if he is well aware of the network structure. The problems occurred in hardware and software is not difficult to deal with because there are plenty of options available in market to make appropriate adjustments. The first step you can take to rectify your network is to make the list of software applications and hardware devices. Second step would be to identify the problems and third step is to identifying the ways of troubleshooting. While one is involve in the troubleshooting process he or she can seek the help of experts. In order to resolve the connectivity issues identify any duplication in the IP addresses, provide similar gateway address to all connected PCs, check if the network cables need any repair or they are properly attached to the network switches and LAN cards. Identify the firewall settings and make sure the traffic which is going out and coming in is not hindered. Make sure you provide accurate proxy server settings in order to connect to the internet. Try to reduce the burden of your network by removing the load of heavy applications. In order to improve the service and performance of your network delete unwanted shortcuts, get rid of the low memory, divide the network in subnets to distribute the load of the entire network, try to clear browsers history on regular basis. It is sometimes considerable to increase the physical memory, remove unnecessary softwares from the system, make use of 10/100 Mbps LAN card support and connect the network using switches. It is recommended to use switches instead of hubs because switches re an intelligent and versatile device.

Security Concerns

The threat of the network security is above all other network problems. It is important to upgrade and install anti virus to deal with the problems of network security. The use of anti spy ware can also help to reduce the risk of network failures due to security issues. It is also preferable to scan the network regularly for viruses and cookies. Utilize strong encryption and decryption techniques. Provide the users with login and user passwords. Take care of the unauthorized users and restrict their entry in the network. Specify the rules to access internet. Also upgrade the operating system and try to use recent security applications. Try to improve and optimize he computer registry. Restrict unauthorized users by implementing the firewall. It is also important to design a proper security mechanism while configuring a network. Also clear the cookies residing in your network. Moreover try to avoid unnecessary downloading because downloading can bring many viruses, worms and even Trojan horses with it. This can disturb or even violate the smooth working of the network.
