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 :
I worked on the first PC's,delivered from IBM
(because there were not yet any PC-compatibles),
and used the then "Standard Operating System"
DOS ( PC-DOS from IBM and MS-DOS from
- no mouse
- no dropdown menus
- max. 640 KByte memory
(that is KB, NOT MB!)

you needed to know that you type in as
a command:

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
"MS-DOS Prompt" windows
(often also called a "DOS-box") :

Windows 2000 / XP :
On Windows 2000 / XP, you
will need to use the
Command Prompt"
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 display all)

NetBEUI and/or IPX/SPX protocol
See the option "NET DIAG" in the above list ?

Requires Windows95/98/ME on both system.
( This diagnostics is NOT available on Windows2000 / XP, please use PING )
NET DIAG Runs the Microsoft Network Diagnostics program to
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 Server'.

On the other system(s), enter also a DOS-window and type also: net diag:

Again, define the protocol, if you are asked for it.
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 continue
with the
next step of the network setup.

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 )

TCP/IP protocol

The TCP/IP protocol comes with its own diagnostic utility, called : PING.
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", where 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 properly.

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

if I try to : "PING":

there is no answer: A signal was send out to contact it, but no reply.
(in this example I know the reason: there is no system #3 with IP-address
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, start
( If you used a
Personal Firewall, then it is most probably not configured properly ).

There is some more info available on the

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 !
