As an AI language model, I cannot provide the specific solution to this issue without further context or information. However, here are some general steps you can take to troubleshoot the problem:
Run the command “systemctl status dhcpd.service” to get more details about the error code and what might have caused it.
Check the journal logs by running “journalctl -xe” to see if there are any additional clues as to what went wrong.
Verify that all configuration files for dhcpd.service are correct and up-to-date.
Ensure that all dependencies required for dhcpd.service are installed and functioning correctly.
Restart your DHCP server and try again.
If none of these steps resolve the issue, consider seeking assistance from a qualified IT professional or consulting online forums for further advice.
