I need to be able to stop and start the Dhcp Client service

Question

For something I am working on, I need to be able to stop and start the Dhcp Client service. However, when I attempt to do so through elevated command prompt I am greeted with System error 5 has occurred and Access is denied. I believe the error is caused when Windows tries to stop the WinHttpAutoProxySvc since that is one of its dependencies, I am trying this on a windows server 2019 with an administrator account.

What can i do to fix it?

If I go directly to services, the control options for WinHttpAutoProxySvc appear disabled.

Answer 1

You'll need to edit the registry, navigate to
HKLM\System\CurrentControlSet\Services\WinHttpAutoProxySvc
then set the "Start" DWORD to Value = 4 (Disabled) and reboot.
