Workshop

As optimistic as we’d all like to be, you won’t always run into clear-cut situations. Sometimes the
network isn’t down for everybody. When the network infrastructure is not totally misbehaving, some of
your calls will come from users who have gotten various illegal operation errors. Perhaps a user will
report to you that he printed, but nothing came out.
Some network problems aren’t directly related to the network protocol or physical network attributes.
These problems are generally thought of as application problems, whether they’re client/server programs
or file and print–oriented programs. We’ll do a lot of in-depth application troubleshooting in Hour 18,
“Lots of Different People in Your Neighborhood: In-Depth Application Troubleshooting.” Be sure to
bring coffee and a hankering to tinker!
