EXPLANATION
Complete this lab as follows: Troubleshoot 1. From the Exec computer, begin troubleshooting by verifying the scope of the connectivity problem. a. Under Executive Office, select Exec. b. Right-click Start and then select Windows PowerShell (Admin). c. From the PowerShell prompt, run the following ping commands. Press Enter after each command: ping 192.168.0 (CorpServer) ping 198.28.2 (The Internet Service Provider, or ISP) Notice that both pings are unsuccessful. ping ITAdmin (the name of the computer in the IT Administration office). Notice that the ping to ITAdmin is successful. However, it is responding using an APIPA IP address. This indicates that this computer is not getting its IP address from the DHCP as it should. 2. From CorpServer computer, continue troubleshooting the problem by trying to access the ISP. a. From the top left, select Floor 1 Overview. b. Under Networking Closet, select CorpServer. c. Right-click Start and then select Windows PowerShell (Admin). d. From the PowerShell prompt, type ping 198.28.2 (the ISP). Notice that the ping to the ISP is successful. e.

Close the Exhibits and Answer Questions windows. 3. From the ITAdmin computer, continue troubleshooting the problem by trying some additional ping tests. a. From the top left, select Floor 1 Overview. b. Under IT Administration, select ITAdmin. c. Right-click Start and then select Windows PowerShell (Admin). d. From the PowerShell prompt, run the following ping commands. Press Enter after each command: ping 192.168.0 (CorpServer) ping 198.28.2 (the ISP) Notice that the ping to the ISP fails. ping exec (the name of the computer in the Executive Office) Notice that the ping to the ITAdmin is successful. However, the Exec computer is responding with an APIPA IP address. e. From the top right, select Answer Questions. f. Answer Question 2. 4. From ITAdmin, use the ipconfig /all command to continue troubleshooting. a. From the PowerShell prompt, type ipconfig /all and press Enter. b. Answer Questions 3 and 4. 5. From Exec, use the ipconfig /all command to continue troubleshooting. a. From the top left, select Floor 1 Overview. b. Under Executive Office, select Exec. c. From the PowerShell prompt, type ipconfig /all and press Enter. d. Answer Questions 5. e. Minimize the Lab Questions dialog. Fix the Issue Since it appears that the DHCP server is not functioning correctly, check the current state of the DHCP services.
- Access the CorpDHCP virtual server. a. From the top left, select Floor 1 Overview. b. Under Networking Closet, select CorpServer. c. From Hyper-V Manager, select CORPSERVER. d. Maximize the window to view all virtual machines. e. Double-click CorpDHCP to connect to the server.
- Confirm that the DHCP service is enabled and activated for the local network. a. From Server Manager, select Tools > DHCP to start the DHCP console. b. Maximize the window for better viewing. c. Expand CorpDHCP.CorpNet > IPv4. The down arrow for Scope [192.168.0] Subnet1 indicates that the scope is not active. d. Right-click Scope [192.168.0] Subnet1 and select Activate. The down arrow for the scope is gone, and the DHCP service for the local network is now active.
- Verify the fix by viewing the IP information for Exec and using the ping command. a. From the top left, select Floor 1 Overview. b. Under Executive Office, select Exec. c. From the PowerShell prompt, type ipconfig /all and press Enter to check the Ethernet configuration. Notice the lines for the default gateway, DNS server, and DHCP server are now configured, along with a new IP address within the DHCP scope for the local network. d. From the PowerShell prompt, type ping 198.28.2 and press Enter. Notice that the ping to the ISP succeeds. e. From the PowerShell prompt, type tracert 198.28.2 and press Enter. f. (Optional) Repeat step 3 for the ITAdmin computer. g. From the top right, select Answer Questions. h. Select Score Lab.
