Now, suppose that Hub 1 controls PCs 1 through 8, Hub 2 controls PCs 9 through 16, and Hub 3 controls PCs 17 through 24. Figure D Failures among switching devices often affect groups of computers. Obviously, if Hub 3 fails, PCs 17 through 24 will malfunction. If a group of PCs malfunctions simultaneously, you should compile a list of the switching devices they have in common with one another but not with the rest of the network. Although we've used hubs in our example, this principle holds true with bridges, routers, and gateways as well.
Many people feel intimidated when it comes to troubleshooting a server.
However, you should keep in mind that Windows NT Server and Windows NT Workstation function identically. If your server is having trouble accessing the rest of the network, you should apply the same troubleshooting techniques we've discussed for troubleshooting a workstation. In this article, we've discussed several common network problems. We've also provided you with methods you can use to work through these problems.
