HOW MANY COMPUTERS ARE AFFECTED BY THIS PROBLEM

2. How many computers are affected by this problem? If the issue is isolated to a single computer, it is likely that the cause of the problem will be related to the computer itself. If it is affecting all computers on a particular subnet or those connected to a particular hub or switch, you can use this information to help you in the troubleshooting process. You can probably tell from this that your troubleshooting will be far more successful if you have detailed information about your network’s physical topology. Because of this, one of the most critical documents you can have on hand when troubleshooting, is a network dia-gram detailing the physical layout of your network. You should also maintain some type of database containing the IP address configuration of your routers, switches, servers, and worksta-tions.
