I am trying to set the "DNS Client" service (also called dnscache) in Windows 10 to DISABLED.

However, when I enter into the services control for Windows the options to manipulate it are all "greyed out".

windows services controls options greyed out

I have also tried to terminate it from the Task Manager, but it throws up an error message saying that it is a matter of "access denied" (I'm running in a test box, as the sole administrative user).

I have also attempted to kill it from the command line as such: taskkill /F /PID 3953 Doing this successfully kills the service but only for a split second! It then reappears immediately under a new PID.

How can I set the DNS Client (dnscache) to being disabled?

  • So what is it that you’re actually trying to accomplish? Disabling the Windows DNS resolver isn’t exactly going to solve anything. – Daniel B Dec 17 '17 at 20:27
  • This service can definitely be stopped. Are you running Task Manager or the services console as administrator? – Patrick Seymour Dec 17 '17 at 20:28
  • I'm having the same issue, nothing I try is able to restart DNS client, I can't even change the logon user. If anybody finds a way to restart network services, plz help! – Hikari May 21 at 17:47

Note that the DNS Client does more than just cache DNS records - it gets them in the first place, so disabling it may limit internet access.

If you still decide to disable it, do this :

  • Use regedit to navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Dnscache,
  • Locate the Start registry key and change its value from 2 (Automatic) to 4 (Disabled)
  • Reboot.

Another method is :

  • Start a Command prompt (cmd) as SYSTEM (psexec -sid cmd.exe)
  • Launch services.msc from it
  • The Startup type drop-down now becomes enabled.

  • Thank you very much for this detailed explanation. I have disabled it via the registry editor now. Further: I am testing some custom DNS settings locally so this service was interfering. – Jack Feschuk Dec 17 '17 at 22:34

    Damn. Now that I've upgraded to Windows 10 Version 1803, I'm having this problem where I can't stop or restart the "DNS Client" service. Although your answer looked promising, launching services.msc as Admin (or from running .\PsExec64.exe -sid cmd.exe and then services.msc) doesn't seem to help me. – Ryan Aug 10 '18 at 23:39

    @Ryan confirmed. This does not work with recent upgrades to Windows, even when posing as local system via the psexec trick. – 0xC0000022L Jun 24 '19 at 9:25
  • Also noticed that apparently without the DNS Client service (dnscache) the DNS suffix list is no longer shown in ipconfig /all. Not sure whether it still takes effect, though. – 0xC0000022L Jun 24 '19 at 10:09
  • This does not explain why the options are greyed out, and how to un-grey them, though, so: sort of useful, but how does one fix this problem instead of working around it via the registry? – Mike 'Pomax' Kamermans Feb 18 at 0:29

In addition to harrymc's answer, I found this while searching for the same problem :

Deactivate :

REG add "HKLM\SYSTEM\CurrentControlSet\services\Dnscache" /v Start /t REG_DWORD /d 4 /f

Automatic mode :

REG add "HKLM\SYSTEM\CurrentControlSet\services\Dnscache" /v Start /t REG_DWORD /d 2 /f
