Troubleshooting computer network is
one of the most important job description for network administrators, system
administrators, network technicians and IT consultants. A computer network may
have different types of problems as being infected with viruses and spyware,
hacker attacks, can access by unauthorized users and may Connectivity problems
due to failure of the faulty network devices or configurations face. The
following is a list of basic network troubleshooting commands that are built
into the Windows-based operating systems and UNIX etc. The right use of these
commands can troubleshooting helps a lot in the diagnosis and solution of
problems with your computer network.
PING
Ping is the most important
troubleshooting command and checks the connectivity with other computers. For
example, your system’s IP address is 10.10.10.10 and your network server’s IP
address is 10.10.10.1 and you can check the connection to the server by using
the ping command in the following format.
At DOS command prompt, type ping 10.10.10.1 and press Enter
When you receive the response from the server then the connectivity is ok and if you get the error message like this means to get “Request time out” so that there is a problem in connecting to the server.
At DOS command prompt, type ping 10.10.10.1 and press Enter
When you receive the response from the server then the connectivity is ok and if you get the error message like this means to get “Request time out” so that there is a problem in connecting to the server.
IPCONFIG
IPconfig is another important
command in Windows. It shows the IP address of the computer and it shows the
DNS, DHCP, Gateway addresses the network and subnet mask.
At DOS prompt type ipconfig and press Enter to see the IP address of your computer.
inconfig In DOS prompt / all and press Enter to display the detailed information.
At DOS prompt type ipconfig and press Enter to see the IP address of your computer.
inconfig In DOS prompt / all and press Enter to display the detailed information.
NSLOOKUP
NSLOOKUP is a TCP / IP-based command
and checks domain name aliases, DNS records, information on the operating
system by query the Internet domain name server. You can correct the error with
the DNS server on your network
HOST NAME
Hostname command shows you the name
of the computer.
At DOS prompt hostname and press Enter
At DOS prompt hostname and press Enter
NETSTAT
NETSTAT utility shows a statistical
protocols and the current established TCP / IP connections to the computer.
NBTSTAT
NBTSTAT helps to resolve the NetBIOS
name resolution problems.
ARP
ARP displays and modifies IP Physical address translation table that is used by the ARP protocols.

FINGER
Finger command is used to retrieve
information about a user on a network.
TRACERT
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 see how many hops (routers) are
involved to achieve, www.yahoo.com, and what the IP address of each hop is then
to use the following command.
At the command prompt, type tracert www.yahoo.com you a list of all the hops and their IP addresses to see.
At the command prompt, type tracert www.yahoo.com you a list of all the hops and their IP addresses to see.
TRACE ROUTE
Traceroute is a very useful network
debugging command and it is in the search for the server slows down the
transmission on the Internet and it also shows the distance between the two
systems are used.
ROUTE
Route command, you can manually make
entries in the routing table.
Hopefully, the above commands will help you diagnose the troubleshooting computer networking problems.
