120 | Lesson 5 S K I L L S U M M A R Y I N THIS LESSON , YOU LEARNED HOW TO : • Work with the command prompt as an administrator and in an efficient manner. • Use basic TCPIP commands such as ipconfig and ping to analyze and test a network. • Use more advanced commands such as netstat, nbtstat, tracert, pathping, route, and netsh to fully examine a computer and configure it in the command line. • Work with the Net command in an effort to find out more information about a system, start and stop services, and work with the network configuration. Table 5-1 continued C OMMAND D ESCRIPTION Pathping Similar to tracert, but also computes the degree of packet loss. NSLookup Displays information about DNS names and their corresponding IP addresses and can be used to diagnose DNS servers. FTP Is an application layer protocol as well as an application.
