    regedit
    Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCPServer\Parameters
    BackupDatabasePath = C:\Windows\System32\dhcp\backup

    or

    CMD run as Administrator

    reg add "HKLM\SYSTEM\CurrentControlSet\Services\DHCPServer\Parameters" /v BackupDatabasePath /t REG_EXPAND_SZ /d "C:\Windows\System32\dhcp\backup" /f

    sc start DHCPServer

    Step 2 works for me on windows 10.
    However, I have a follow up question..
    Is there a security risks if 'NETWORK SERVICE'
    will be granted a full permission ?

    Just wanted to say thank you!
    Step 2 (setting correct permissions on registry keys) solved the problem on Windows 10.

    Not sure how it occurred, but I installed various programs, such as 7+ Taskbar Tweaker, Classic Shell, WinMerge, etc, but no anti-virus, and after reboot, network and internet access failed to work.

    For others: I got "access denied" or "service terminated with access denied" messages in EventLog for numerous services…

    DHCP
    Base Filtering Engine
    Windows Defender Firewall

    As mentioned in this article, after setting permissions for the DHCP services, it automatically started up and the network came to life again.
    But EventLog still showed errors with the above services, along with the "Network Location Awareness" service.
    So for the "Base Filtering Engine", I set permissions on the BFE key to users "LOCAL SERVICE" and "NT SERVICE\bfe" and granted full permissions to those.

    Things were still broken, so in frustration, on the root "Services" folder (HKLM\SYSTEM\CurrentControlSet\Services) I again granted full permissions to "LOCAL SERVICE" and "NETWORK SERVICE".

    But the other thing that fixed the broken Firewall (mpssvc) was granting full permission to "NT SERVICE\mpssvc" on the 2 folders:
    HKLM\SYSTEM\CurrentControlSet\Services\mpssvc
    HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess

    Hope this also helps out others.

    On my sister's Toshiba laptop running Windows7,
    the first option failed to fix the problem.
    The second option Worked Perfectly, and took much less time!

    Thanks…

    Followed all to a T but DHCP won't just work. Have dug out and executed all cmd and service checks I could, from winsock to dns flush and ipv$ reset. It just won't work.
