Windows 10: ipconfig /renew returns Unable to Contact DHCP Server. DHCP Access Denied. A million errors...

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.

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.

Cannot ipconfig /renew

Whenever I try to ipconfig /renew (after ipconfig /release), it takes a long time and then it says that "An error occurred while renewing interface Npcap Loopback Adapter: unable to contact your DHCP server. Request has been timed out" Any suggestions
on how to fix this?

 

Unable to contact your DHCP server.

Good evening.

I have a simple yet complicated Problem. My Computer logs onto the internet just fine but will only load sites like Wikipedia, Google and Youtube.

It appears that Ipv6 connects just fine but when I check for device info (provided by router admin access) it shows my computers IPv4 as 0.0.0.0.

When I go into CMD and type ipconfig/renew it is unable to contact the DHCP server. The Resquest times out.

On ipconfig/all it says my WLaN adapter does not have DHCP enabled, but according to settings it does?

I’ve tried the Netsh commands, restarting PC and Router, Re-enabling my adapter, changing IP to a static one but to no avail.

Any help would be appreciated.

 

DHCP will not start . Error 5.

Have not been able to get automatic IP on LAN because DHCP won't start .
The error message when trying to restart DHCP is :
"Windows was unable to restart DHCP Client service . Error 5 : Access Denied."
I am able to connect to the internet with a static IP .
I have no restoration points on my computer .

This is what I have tried so far -->

The usual commands :

• ipconfig /flushdns
• netsh int ip reset c:\resetlog.txt
• netsh winsock reset catalog
• netsh int tcp set heuristics disabled
• netsh int tcp set global autotuninglevel=disabled
• netsh int tcp set global rss=enabled
• ipconfig / release
• ipconfig /renew

I have , of course , contacted my ISP and they have found nothing wrong on their side (or in the router) .


I have also uninstalled / reinstalled my network adaptor .

Have also tried modifying the registry by assigning permissions at :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCP\


Now digging deeper , I set the command :
CMD /K SC QC DHCP


This was what I got (note the system is in Spanish) :
TIPO_INICIO : 2 AUTO_START
CONTROL_ERROR : 1 NORMAL
NOMBRE_RUTA_BINARIO : C:\Windows\system32\svchlst.exe -k LocalServiceNetworkRestricted
GRUPO_ORDEN_CARGA : TDI
ETIQUETA : 0
NOMBRE_MOSTRAR : Cliente DHCP
DEPENDENCIAS : MSI
TDX
AFD
NOMBRE_INICIO_SERVICIO : NT Authority\LocalService

Any ideas? ,
Thanks .
