TCP/IP Utilities
The TCP/IP protocol provides a set of utilities to help
diagnose and isolate network problems.
IPconfig
This command verifies the local machine's TCP/IP
configuration parameters:
NOTE: To record the IP settings to a text file on
floppy, use the command:
ipconfig /all >a:\ipinfo.txt
Ping
The Ping command sends a small signal to a known
TCP/IP address to test whether a particular TCP/IP host
is available and functional. If the remote computer is
available on the network it will send a response back to
the local computer with the following message repeated
four times: Reply from IP_address....
Step Action
1. Click on Start >All Programs
>Accessories >Command Prompt.
The Command Prompt window opens.
2. Type ipconfig /all and press <Enter>.
The system reports the local computer’s IP
address, subnet mask, default gateway, a
description of the network adapter, the
physical (MAC) address, and the status of
network services such as DNS and DHCP,
as they pertain to the network adapter.
Step Action
1. Click on Start/Programs/
Command Prompt.
The Command Prompt window opens.
2. Type ping IP_address and press <Enter>.
(where IP_address is the address of a
remote computer.) A successful reply
indicates that you can talk to the remote
computer.
If the ping is not successful, try the
following steps.
3. Type ping 127.0.0.1 (loop back address)
and press <Enter>.
A successful reply indicates that TCP/IP is
installed and loaded correctly on the local
computer.
4. Ping the IP address of your computer to
verify it was added correctly and to check
for possible duplicate IP addresses.
5. Ping the IP addresses for the other stations
on your network to verify they are present.
