4. Click the Ping tab, and do the following:

   

   1. Enter the IP address, DNS-registered hostname, or WINS-registered hostname of the target.
   2. Click Start.
      The data area displays the ping response messages. The ping command sends one echo request per second, calculates round-trip times and packet loss statistics, and displays a brief summary upon completing the calculation. If the host is operational and on the network, it responds to the echo request. By default, echo requests are sent until interrupted by clicking Stop.
   NOTE

   Ping sends an echo request to a network host. The host parameter is either a valid hostname or an IP address. If the host is operational and on the network, it responds to the echo request. Ping sends one echo request per second and calculates round-trip times and packet loss statistics. It displays a brief summary upon completion of the calculation.

   NOTE Not all network equipment responds to ping packets, as it is a common mechanism that is used in denial-of-service attacks. Lack of response does not necessarily indicate that the target of the ping is unusable for other purposes.
5. Click the Trace Route tab, and do the following:

   

   1. Enter the IP address, DNS-registered hostname, or WINS-registered hostname of the target.
   2. Click Start.
      The data area displays round-trip response time and identifying information for each device in the path.

   The tracert utility traces the path from your thin client to a network host. The host parameter is either a valid hostname or an IP address. The tracert utility sends out a packet of information three times to each device (routers and computers) in the path. The round-trip response time and the identifier information are displayed in the message box.

6. Click the Telnet tab, and do the following:

   

   1. Click Telnet.
   2. Enter the hostname.
   3. Enter a port number.
