There are several ways to perform a shutdown of a computing system.  This lesson examines the different methods of correctly shutting down a computing system.  We explain what happens when the shutdown process encounters an error, and what actions the operating system takes when Windows Shutdown is performed incorrectly.  We also demonstrate the various ways in which local and remote systems can be properly shutdown.

Tracert Lab

Tracert Lab

In this lab lesson you’ll learn about Tracert (Trace Route). Trace Route is a command line utility that provides packet trace information between two endpoints, your destination and your target.
