Testing Connection using 'NET DIAG'

Once you have setup your network and it does not work, you will need to determine, whether you have a 'hardware' problem (network-board, cables,..) or a software problem (drivers, sharing,...).
When you install a Windows95 networking, also some command-line programs are installed. The 'net' command offers a lot of parameters, but has a powerful diagnostic option (you can also you the
TCP/IP 'ping' test):

On the first system, open a DOS-windows and 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 install a '
Diagnostic Server'.

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

Again, define the protocol,if 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, then you need to check the software-setup.

If you are asked again, whether the 'Diagnostic server is already running', then there was no communication and you have to check your hardware.
