There can be different sorts of problems that can arose due to network malfunction in various hardware and software components of a network. Networks can be of different types. From home to corporate Networks, each network type has its own errors and remedies. A simple Network troubleshooting starts from pinging your nearest IP address in your subnet. You should try to ping local host from command prompt. The address for local host is 127.0.0.1 and then tries to ping your own IP Address. If both loopback adapter and Network interface return true (send replies) then assume your own physical pc is ok

To check the connectivity of other computer(s), try to ping them and find out about their connectivity. There can be many methods and software techniques to resolve network issues.

You can check your network card’s hardware status to find out its connectivity. There are certain permissions checking techniques that can be used for network diagnostics. “Netsh” command in windows offers many measures to locate problems in Networks.

To resolve connectivity issues, you must check the gateway and DNS settings. In advanced settings, you can also set the WINS server, which stands for Windows Internet Naming Server.

SNMP (Simple Network Management Protocol) is a valuable tool for Network Diagnostics through SNMP Strings. It can not only check the status of each node.

You can not only check status of each connected node but can set certain triggers and alarms against specific actions or lost connectivity in the network.

Besides SNMP, in a Domain Environment, you can use windows OS own commands to check for Network errors. First you must install afminpak.msi on Start>run and then use its commands liker “dcdiag” or “netdiag” to chweck for connectivity and validity of service operations.

Active Directory Administrative Management (ADAM) can also be used to detect and diagnose the problems ion Active Directory Structure.

In case of a broadband connection, you must first verify the settings provided by Service Provider and check them against your own settings. Then verify the physical connectivity between both ends.

Most of the times, the errors are in drop line also known as local loop. Sometimes there are hardware errors in Modem or Router which must be addressed by a physical replacement of equipment.

All the Network Management Software can detect errors in Network and help to locate the faulty node in Network which will in turn facilitate greatly in Network troubleshooting.
