A company\'s network is experiencing heavy traffic that
performance across the LAN is suffering. They suspect
that one device is issuing a barrage of requests, perhaps
due to a software application malfunctioning, a security
breach, or a virus, but they are unable to identify the
problem node. Using TCP/IP utility knowledge, what
command(s) could you use to identify the troublesome
computer\'s IP address and host name? What single
command would give the most informations about where
traffic is slowing?
Solution
PING
The Packet Internet Groper (PING) tool is very familiar to
most IT pros. As with all TCP/IP utilities, it must be run
from the command line. It is used to verify a connection to
a remote computer, router, or printer (or anything that uses
a TCP/IP address). The PING tool sends small packets of
data to the remote system requesting a reply and then
displays the results of the reply.
If a PING test shows a reply, then you know you have a
physical link to the remote system.
The problem could be caused by a number of factors.

Check to see that the remote system is not powered down,
that there is not a piece of communication equipment
between your system and a remote system that is down,
and that you have the correct IP address. If none of these
factors seems to be culprit, youll need to switch tools and
use the TRACERT tool instead, which is discussed below.
Besides verifying TCP/IP connections, the PING command
can also be used to test your DNS servers,
By pinging the friendly name of the remote location, your
DNS servers should automatically resolve the friendly
name to an IP address,
However, if your DNS servers are not responding, or the
name you are trying to reach does not exist, you will
receive a response
This lets you know that there is a DNS issue that needs
further attention.
The PING tool can also allow you to check your network
card. By pinging the IP address of 127.0.0.1, the command
will send a PING request to your network card to see if it
replies.
TRACERT
The next tool we will look at is the TRACERT (trace route)
tool. The TRACERT tool shows the route taken by a packet
of data to the destination IP address (or friendly name).
This shows that the packet you sent arrived at the
