A small business owner learns that some users are unable to access a website. All PCs are configured with static IP addressing. Use the ping command to identify the issue.

Step 1: Verify connectivity.

Access the Desktop tab > Web Browser of each PC and enter the URL www.cisco.pka. Identify any PCs that are not connecting to the web server.

Note: All of the devices require time to complete the boot process. Please allow up to one minute before receiving a web response.

Step 2: Ping the web server from PC2.

  2. Type ping www.cisco.pka.
    Did the ping return a reply? What is the IP address displayed in the reply, if any?____________________________________________________________________________________
    There was no reply. No IP address was displayed in the message.

Step 3: Ping the web server from PC1.
