Windows 10: DHCP server cannot update A records, access denied

Under normal situation when DHCP performing dynamic updates on behalf, the server itself has write permission to the records.But if client machine initiate a dns update eg. manually run ipconfig /registerdns, the A record resulted is not updatable by DHCP server eg. when IP changed on the machine.Is there any workaround, or any way to make DHCP server writable on all A records?

FIXED: ipconfig /renew returns Unable to Contact DHCP Server. DHCP Access Denied. A million errors with no solution.

There are steps here to try for DHCP giving Access Denied:

I have tried most of them since they cover some of the same steps, except for reinstalling Windows 10. I think my problem might be with the fact that trying to restart/stop the DHCP service says access denied? I have no idea why that happens and I've tried
giving the permissions to DHCP and Network Service, as well as full control to my user and such nothing seems to work with that service.

Hello I've recently changed ISPs and my ISP is telling me that everything is configured in their end but I still have Unidentified Network and running a diagnose says "Ethernet doesn't have a valid IP configuration".

To solve this I found online that maybe running ipconfig /release then /renew might do it but it didn't, I get the message "An error occurred while renewing interface Ethernet : unable to contact your DHCP
server. Request has timed out."

I've tried multiple things to solve this and none of them have worked, these include:

• Running ipconfig /registerdns: this simply said "Registration of the DNS resource records for all adapters of this computer has been initiated. Any errors will be reported in the Event Viewer in 15 minutes."
• Going into services.msc, finding DHCP and restarting/stopping it: This shows a box with the following: "When DHCP Client stops, there other services will also stop -WinHTTP Web Proxy Auto-Discovery Service, Network Connected Devices Auto-Setup, Network
  List Service, Network Location Awareness" and if I want to stop them so I click yes only to be greeted by the message: "Windows could not stop the DHCP Client service on Local Computer. Error 5: Access is denied."
• Trying to solve the above, I've had to go into regedit and change permissions for DHCP and TCPIP, I followed many instructions online and none of them have worked.
• Running netsh winsock reset: After running this it told me to restart so I did and the result was that nothing changed.
• Updating drivers: I tried to update my network drivers and it says they're up to date, I can't rollback and did confirm these are the latest ones.
• Ran sfc /scannow

If anyone has a solution to this problem I'll be glad to hear it and try anything out, so far nothing seems to work and I'm beginning to wonder if it's a problem on my end or the ISP.

FIXED:

I managed to fix it, here's what I did:

It was some problem with my modem so I had to manually set up the IPv4 settings and the default gateway to be able to change the configuration from inside.
