I'd be happy to help you out with your question. Sorry for the inconvenience caused.
Please try following self troubleshooting steps to resolve this issue :-
Verify the hostname: Please ensure that you have entered the correct hostname for the machine you are trying to ping. It's important to double-check the spelling and capitalization to avoid any errors.
Check DNS configuration: Let's verify the DNS server configuration on the problematic machine. To do this, follow these steps:
a. Go to the "Network and Sharing Center" by right-clicking on the network icon in the system tray and selecting "Open Network & Internet settings."
b. Click on "Change adapter options" to open the Network Connections window.
c. Right-click on the network adapter in use and select "Properties."
d. Double-click on "Internet Protocol Version 4 (TCP/IPv4)" in the list.
e. Ensure that the DNS server settings are set correctly. If you are unsure, you can compare them to a working machine or consult your network administrator.
Flush DNS cache: To refresh the DNS resolver cache on your computer, follow these steps:
a. Press the Windows key and type "Command Prompt" in the search bar.
b. Right-click on "Command Prompt" and select "Run as administrator."
c. In the Command Prompt window, type the command: ipconfig /flushdns and press Enter.
d. Wait for the process to complete, and then try pinging the problematic machine again.
Check DNS server connectivity: Let's ensure that your computer can reach the DNS server. You can do this by following these steps:
a. Open the Command Prompt as an administrator.
b. Type the command: ping <DNS server IP address> and press Enter.
c. Replace <DNS server IP address> with the actual IP address of your DNS server.
d. If you receive responses from the server, it indicates successful connectivity. If not, there might be an issue with your network configuration or connectivity.
Check DNS server settings: If your DNS server settings are manually configured, it's crucial to verify that they are accurate. If they are automatically assigned, consider switching to manual DNS settings and using a reliable DNS server such as Google DNS (18.104.22.168 and 22.214.171.124).
Verify hostname registration: It's possible that the hostname of the problematic machine is not properly registered in the DNS server. To resolve this, you may need to add the hostname and its associated IP address manually in the DNS server configuration. Please consult your network administrator for assistance with this step.
Check firewall settings: In some cases, the Windows Firewall or third-party firewall software on the problematic machine can block ICMP (ping) requests. Temporarily disable the firewall for testing purposes and attempt to ping the machine again. If the ping is successful, adjust the firewall settings accordingly to allow ICMP traffic.
