Disable Windows firewall on 2k19.

Question

Hi everyone!

I am trying to disable the firewall service on w2k19 but I get the following error message below. Why?

Thanks.

Answer 1

Hi,

Thanks for DSPatrick's answer.

Please make sure that you run cmd.exe as administrator to execute command "sc config MpsSvc start= disabled"

If "Access is denied" error still occurred, may I know whether you want to disable Windows Defender Firewall or want to disable Windows Defender Firewall services?

To disable Windows Defender Firewall as image 1:

You can try DSPatrick's suggestion through Powershell with administrator privilege or you can execute the following command through cmd.exe with administrator privilege.

Disable Guest or public networks:

netsh firewall set opmode disable

If your computer is a domain member you must to use this command to disable DOMAIN mode and Local mode:

netsh firewall set opmode mode = DISABLE profile = ALL

To disable Windows Defender Firewall services as image 2:

Please open cmd.exe with administrator privilege and run the following command:

reg add hklm\system\currentcontrolset\services\mpssvc /t reg_dword /v start /d 4 /f

Hope my answer will help you!

Answer 2

You wouldn't want to disable the service. Better to turn off the profile in question.
Set-NetFirewallProfile -Profile Domain,Public,Private -Enabled False
run with elevated credentials would turn all three profiles off.

Answer 3

Hi, thanks for your answer.

So, are the two commands equivalents?

"netsh advfirewall set allprofiles state off" IS THE SAME TO "netsh firewall set opmode mode = DISABLE profile = ALL" OR "netsh firewall set opmode disable" ?

Also, besides Windows Defender Firewall service does exist a Windows Firewall service? Or the firewall job are done by the Defender service?

Thanks.

Answer 4

What is the end goal here? If you simply want the firewall off for all profiles then you can execute (with elevated credentials) PowerShell
Set-NetFirewallProfile -Profile Domain,Public,Private -Enabled False

or from elevated cmd.exe
netsh firewall set opmode mode=disable profile=ALL

Okay, I understood, but is there a Firewall service? Yes or No?

Thanks.
