A practical, hands-on guide to network troubleshooting that emphasizes diagnostic techniques that many professionals, including engineers, architects, doctors, scientists, attorneys, etc. can really relate to. In today's pervasive network environment, many of these people are often responsible for "fixing the network" if it goes down. This book will emphasize fixing practical networking applications like shared printers, using the Internet, and sharing files. It does not get into the specifics of protocols or specific applications (i.e. Lotus Notes), but provides "Reader's Digest" overviews of topics like PC's, Unix, NT, Novell, Routers, and Firewalls, that impart the broad principles behind the technologies. Similarly, it allows readers to troubleshoot their specific applications by imparting broad principles at the expense of implementation specifics.
