Test the Network Connection
You have installed the network card and have verified in the
Device-Manager, that the Network card
is listed as "working properly" ?
You have adjusted
the Network configuration and configured the Network Protocols ?
Before attempting to access data on the other system, I strongly
suggest to use the Diagnostic
tools provided with Windows to verify that the electronics on the
network card working and the
cabling is in good condition.
There is no menu-function to select, no option to be selected, no
button to be pushed,
it required to use the "MS-DOS Prompt"
or "Command Prompt":
| Windows 95/98/ME :

PC's,delivered from IBM
(because there were not yet any PC-compatibles),
and used the then "Standard Operating System"

- no mouse
- no dropdown menus
- max. 640 KByte memory (that
is KB, NOT MB!)
you needed to know that you type in as
Windows95/98 (and I think also ME) still
use MS-DOS version 7 to start the boot-process,
before switching over to the graphical User-
And some jobs can be done better using a DOS-
command, and Windows offers the possibility
to enter such command in the
(often also called a "DOS-box") :
| Windows 2000 / XP :
|On Windows 2000 / XP, you
will need to use the
via Start-menu / Programs / Accessories
I know from experience, that "younger people" (you work
out yourself what I mean with that) very
often have no knowledge of DOS-commands, so here is your chance
for a few of them.
One of the most powerful command (and at the same time) least
known command is : NET
NET is a nice DOS-command, giving you help when you ask for it,
via : NET /help":
( it actually takes more than one
windows to display, I did copy/paste 2 screens together to
and/or IPX/SPX protocol
See the option "NET DIAG" in the above list ?
||Requires Windows95/98/ME on both
( This diagnostics is NOT available on
Windows2000 / XP, please use PING )
||Runs the Microsoft Network Diagnostics
display diagnostic information about your network.
At the prompt, please type: net diag
If multiple protocols are installed, select the
one to be used for the test.
Since this is the first system running the test, there is no
answer from the network.
Answering now with 'N' will have the system act as 'Diagnostic
On the other system(s), enter also a DOS-window and type also: net
Again, define the protocol, if you are asked
If the network hardware is in good condition, the 'net diag' on
this station should now locate the 'Diagnostic Server' on the
other system and display a message like above, you are ready to
with the next step of the
However, if you are asked again, whether the 'Diagnostic server
is already running', then there was
no communication and you have to
check your hardware and cabling
(sorry, start Trouble-Shooting )
The TCP/IP protocol comes with its own diagnostic utility, called
And as soon you install TCP/IP protocol, it install automatically
a diagnostic responder
(so no need as on NET DIAG to first
install a Diagnostic
Server ) : Any system configured with TCP/IP
(a PC, a UNIX-system, a mini-computer, a network printer,...)
has this diagnostic responder and will reply to the PING signal
(exception: systems with a firewall may not
respond to a PING signal )
You did configure
in the previous step the IP-address ?
Type at the prompt: "PING 192.168.1.1", where
192.168.1.1 in this example is the IP-address
of system#1 on my small network:
I am getting a reply back, a network signal passed through my
network card on the network cable
through the network card on the other system, and was then send
back the same way, verifying that
the electronics of the network card is working and the cabling is
|Please, run this test on ALL systems
on your network and PING all other systems !
It is possible that a system can send out PING signals
and reeceives the return signal, while
itself is NOT
responding to a PING signal (as
it can be caused by Personal Firewalls )
If you get an ALL systems a reply, then you are ready to continue.
if I try to : "PING 192.168.1.3":
there is no answer: A signal was send out to contact it, but no
(in this example I know the reason:
there is no system #3 with IP-address 192.168.1.3)
If you have a system configured with this IP-address and it is
powered on and
connected to the network cable and you get no PING-reply: sorry,
( If you used a
Personal Firewall, then it is most
configured properly ).
There is some more info available on the PING-command.
Note: if PING does not work in all directions, then also the NetBIOS
broadcasts will be failing,
and since all Microsoft networking (except the new "Active
Directory" on Windows2000 server )
is based on NetBIOS, your network will NOT work properly !
