Background / Scenario
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.
Which PCs are unable to connect to the web server?_____________ PC2
Step 2: Ping the web server from PC2.
- On PC2, access the Command Prompt from the Desktop tab.
- 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.
- On PC1, access the Command Prompt from the Desktop tab.
- Type ping www.cisco.pka.
- Did the ping return a reply? What is the IP address returned, if any?____________________________________________________________________________________
Reply was returned with 192.15.2.10 as the IP address for www.cisco.pka.
Step 4: Ping the IP address of the web server from PC2.
- On PC2, access the Command Prompt from the Desktop tab.
- Attempt to reach the IP address of the web server with the command ping 192.15.2.10.

- Access the Command Prompt of PC1.
- Using the command ipconfig /all, examine the DNS server configuration on PC1.
- Access the Command Prompt of PC2.
