Using Microsoft net diag to test network connections

The NET.EXE program supplied by Microsoft* with Windows* for Workgroups and Windows* 95 can be used to test network connections between two computers on a network. This method will work regardless of the combination of make, manufacturer or model of network adapters being used. As an added advantage, it also runs using Windows protocol stacks and the adapter's normal driver, providing additional confirmation of network operability.

To use this method, both machines involved in the test must have either the NetBEUI or IPX/SPX compatible protocol (or both) installed. When executing the test, both machines must be running the same protocol.

  1. From the first machine, open a DOS session under Windows.

  2. Within the DOS box, type NET DIAG and press enter.

  3. If you are running both NetBEUI and IPX/SPX, the system should respond with a question asking which protocol to use. Respond with N for NetBEUI, I for IPX/SPX , or E to exit.

  4. If you are running only one of these 2 protocols, then that protocol will be used automatically.

  5. The first computer will respond with the message "Microsoft Network Diagnostics will use (IPX / a NetBIOS provider) No diagnostic servers were detected on the network. Is Microsoft Network Diagnostics currently running on any other computers on the network? (Y/N)."

  6. Answer N to this question. The computer will respond "This computer will now begin acting as a diagnostic server. Press any key to stop acting as a diagnostic server."

  7. Leave the first computer in this state and go to the second computer. Repeat steps 1 through 4, being sure to select the same protocol. The second computer should respond with the message "The diagnostic server has been located on the network. Communicating with the diagnostic server. This may take several seconds. Validating reply from the diagnostic server. The diagnostic server's reply is correct. This indicates that network information is being sent and received properly. Command completed successfully."
