4.7.2. Testing the TCP/IP Network
It is beyond the scope of this Service Manual to cover Networking in detail, there are many excellent manuals on this subject, but
we hope the information in this section will aid with your troubleshooting efforts. In most cases, the Network Administrator will be
able to provide you with needed information or assistance.
When encountering Network problems during an onsite sevice call or during the installation stage, try to isolate the steps that are
not being completed so that you can quickly locate the components that don't work. It is best to organize your troubleshooting
efforts by understanding what should be happening, then you can trace the path and see where the problem is occurring.
In our case, we use TCP/IP for transportation of data from one system to another, which involves a whole series of events occurring
throughout a number of different layers.
As with all networking, TCP/IP works better when its plugged in, therefore, start your troubleshooting by checking the Physical Con-
nectivity first, the cable(s).
In our examples, we'll use several simple tools readily available in the DOS command-line utility for troubleshooting. There are
many other utilities available for checking more detailed information, some are Free of charge, others are available for a nominal
fee.
