Troubleshooting computer network is among the most important job descriptions of the network administrators, system administrators, network technicians and the IT consultants. A computer network can have different kinds of problems such as it can be infected with virus and spyware, attacked by hackers, accessed by unauthorized users and may face connectivity failure issues due to the faulty network devices or configurations.

Following is a list of the basic network troubleshooting commands that are built-in the Windows based operating systems and UNIX etc. The right use of these troubleshooting commands can helps a lot in diagnosing and resolving the issues with windows computer network. few more windows Windows tips.

List of Command used for computer network troubleshooting in windows, Unix, Linux and Macintosh.

1) PING command.

PING full form is Packet INternet Gopher or Packet INter-network Gopher.

Ping is the most important network troubleshooting command and it checks the connectivity with the other computers. For example your system’s IP address is 10.10.10.10 and your network servers’ IP address is 10.10.10.1 and you can check the connectivity with the server by using the Ping command in following format.
At DOS prompt type Ping 10.10.10.1 and press enter.
If you get the reply from the server then the connectivity is OK and if you get the error message like this “Request time out” this means the there is some problem in the connectivity with the server.

2) IPCONFIG command for network repair.

IPCONFIG full form is Internet Protocol CONFIGuration.

IPconfig is another important network problem troubleshooting command in Windows, Unix and Linux. It shows the IP address of the computer and also it shows the DNS, DHCP, Gateway addresses of the network and subnet mask.
At DOS prompt type ipconfig and press enter to see the IP address of your computer.

At DOS prompt type inconfig/all and press enter to see the detailed information.DOS full form is Disk Operating System. DHCP full form is Dynamic Host Control Protocol.

3) NSLOOKUP command to fix Network related problem.

NSLOOKUP full form is Name Server LOOKUP.

NSLOOKUP is a TCP/IP based command and it checks domain name aliases, DNS records, operating system information by sending query to the Internet Domain Name Servers. You can resolve the errors with the DNS of your network server. DNS full form is Domain Name Server.

4) HOSTNAME command for network repairs.

Hostname command shows you the computer name.
At DOS prompt type Hostname and press enter.

5) NETSTAT command for computer networking.

NETSTAT full form is NETwork STATastics.
NETSTAT utility shows the protocols statistics and the current established TCP/IP connections in the computer.

6) NBTSTAT for windows networking.

NBTSTAT helps to troubleshoot the NETBIOS name resolutions problems.

7) ARP command for networking.

ARP full form is Address Resolution Protocol.

ARP displays and modifies IP to Physical address translation table that is used by the ARP protocols.

8) FINGER command for network repair diagnosis.

Finger command is used to retrieve the information about a user on a network.

9) TRACERT command for networking.

TRACERT full form isTRACE RouTe.

Tracert command is used to determine the path of the remote system. This tool also provides the number of hops and the IP address of each hop. For example if you want to see that how many hops (routers) are involved to reach any URL and what’s the IP address of each hop then use the following command.
At command prompt type tracert www.yahoo.com or google.com. You will see a list of all the hops and their IP addresses.

10) TRACEROUTE command for network diagnosis.

Traceroute is a very useful network debugging command and it is used in locating the server that is slowing down the transmission on the internet and it also shows the route between the two systems.

11) ROUTE command for network routing table.

Route command allows you to make manual entries in the routing table.
Hopefully the above mentioned commands will help you to diagnose and troubleshooting computer networking problems.
