Disabling the Windows Firewall in Windows Server 2019 can be done through the graphical user interface (GUI) provided by the operating system. Here are the steps to follow:

  • Open the «Server Manager» application by clicking the Start button and typing «Server Manager» in the search box.
  • In the Server Manager window, click on «Local Server» on the left-hand side.
  • Locate the «Windows Firewall» section and click on the link labeled «On» next to it. This will open the Windows Firewall settings.
  • In the Windows Firewall settings, select the «Turn Off Windows Firewall» option for both the «Domain network» and «Private network» categories.
  • Click «OK» to save the changes.

By following these steps, you can disable the Windows Firewall using the GUI interface in Windows Server 2019.

Considerations When Disabling the Firewall

While disabling the firewall temporarily can be necessary in certain situations, it is important to consider the potential risks and implications it might have on your server’s security. Here are a few points to keep in mind:

  • Disabling the firewall exposes your server to potential security threats from the network.
  • It is recommended to only disable the firewall for a short period and to re-enable it as soon as the necessary tasks are completed.
  • Make sure to monitor the server closely and implement other security measures to compensate for the temporary disabling of the firewall.
  • Be aware of the specific requirements of any applications or services running on the server that may rely on the Windows Firewall for proper functioning.

Considering these factors will help maintain the overall security and stability of your Windows Server 2019 environment.

Method 2: Disabling Firewall Using PowerShell

An alternative method to disable the Windows Firewall in Windows Server 2019 is by using PowerShell, a powerful command-line tool. Here’s how you can do it:

  • Open PowerShell as an administrator by right-clicking the Start button and selecting «Windows PowerShell (Admin)».
  • Run the following command to disable the Windows Firewall:
    Set-NetFirewallProfile -Profile Domain,Public,Private -Enabled False
  • After executing the command, the Windows Firewall will be disabled on all network profiles (Domain, Public, and Private).

Using PowerShell provides a quick and efficient way to disable the firewall in Windows Server 2019.

Remember the Consequences

While PowerShell offers convenience and flexibility, it’s essential to understand the consequences of disabling the firewall:

  • Disabling the firewall removes a crucial layer of protection for your server and makes it more vulnerable.
  • Ensure that you have other security measures in place to compensate for the temporary removal of the firewall.
  • Regularly monitor the server for any abnormal network activity and promptly re-enable the firewall when it is no longer required to reduce the risk to your server.

By being proactive and vigilant, you can maintain a secure environment even when temporarily disabling the firewall using PowerShell.

Exploring Additional Firewall Configuration Options

Windows Server 2019 offers various firewall configuration options beyond simply enabling or disabling it. Let’s explore a few additional aspects:

1. Creating Custom Firewall Rules

In addition to disabling or enabling the Windows Firewall, you can customize the rules to allow or block specific network traffic based on your requirements. This allows you to have more granular control over the communication between your server and the outside world.

You can create custom firewall rules through the Windows Firewall with Advanced Security interface or by using PowerShell commands. These rules can define various parameters, such as specific protocols, ports, IP addresses, and more.

Custom firewall rules can help you tailor the server’s network access to your specific needs, promoting both security and flexibility.

Example: Creating a Firewall Rule in PowerShell

Here’s an example of how you can create a custom firewall rule using PowerShell:

Command Description
New-NetFirewallRule -DisplayName «Allow HTTP Traffic» -Direction Inbound -Protocol TCP -LocalPort 80 -Action Allow This command creates a new inbound firewall rule that allows TCP traffic on port 80 (HTTP).

Using PowerShell, you can create highly specific firewall rules to meet your server’s unique requirements.

2. Using Group Policy to Manage Firewall Settings

In an enterprise environment with multiple Windows Server 2019 systems, it may be more efficient to manage firewall settings using Group Policy. Group Policy allows central management of firewall rules across multiple servers, ensuring consistency and easy deployment of configurations.

Group Policy provides a unified approach to manage firewall settings across multiple servers, saving administrators time and effort in maintaining a secure network infrastructure.

Using Group Policy Object (GPO) to Manage Firewall Rules

To manage firewall settings through Group Policy, you can follow these general steps:

  • Create a new Group Policy Object (GPO) or use an existing one.
  • Edit the GPO and navigate to «Computer Configuration» -> «Policies» -> «Windows Settings» -> «Security Settings» -> «Windows Firewall with Advanced Security».
  • Configure the desired firewall rules and settings within the GPO.
  • Link the GPO to the appropriate Organizational Unit (OU) or group of computers.
  • Update the Group Policy on the target servers for the changes to take effect.

Using Group Policy to manage firewall settings provides a centralized and efficient way to maintain security and consistency across multiple Windows Server 2019 systems.

Conclusion

Disabling the Windows Firewall in Windows Server 2019 can be necessary in certain situations, but it’s crucial to understand the potential risks and consequences. Whether you choose to disable the Firewall temporarily using the GUI interface or PowerShell, it is essential to only do so when required and implement other security measures to compensate for the reduced protection.

Заходим в наш сервер. Открывается консоль

Введем в консоли команду

netsh advfirewall set allprofiles state off

После этого сервер отключит Firewall.

Включение Firewall

Для включение обратная команда

netsh advfirewall set allprofiles state on

Заключение

Как видим из заметки отключаются все профили Firewall. Я не рекомендую оставлять сервер в таком виде в боевом режиме. Я использую этот режим, только для настройки сервера. После настройки сервера, я настраиваю Firewall и включаю его обратно.

If you need to install some third-party applications on Windows 2019 server, which require connectivity among other clients and servers, you need to check the status of the built-in firewall. In few cases, you can open/allow certain ports in the firewall policy, but in other cases, you need to disable the firewall to make the application work properly.

Disabling Windows firewall used to be an easy option on earlier Operating Systems by just switching off the ‘Windows Firewall’ service in computer management. Unfortunately, you will not find the same ‘Windows Firewall’ service in Windows 2019 server. Since Windows Defender manages the network firewall on Windows 2019 server, we can’t see a separate service to disable it.

That doesn’t mean we can’t disable the Windows firewall on the 2019 server. There are plenty of ways to do it from GUI, CMD and Powershell. I’m not going to cover those steps here. I’m mainly targeting the steps you may need to perform if the Windows firewall policy is managed by your administrator (via the Domain policy). In this case, whatever actions you perform on the local computer to disable the firewall will not work if the server is part of the domain network.

Windows Firewall Service in Windows 2019:

As shown below, it was replaced with Windows Defender Firewall, and we will not have the option to stop and change the state to Disable/Manual.

Windows Defender Firewall On 2019 Server

Meanwhile, here is the state from Windows 2012 R2 server where we can stop the service and disable it. So, the Windows firewall will be disabled permanently on the server for any type of network profile.

2012 R2 Server Firewall

The Trick to Disable Firewall on Windows 2019 Server – When it is managed by your administrator

Let’s dive to the working steps.

Find out the correct network profile server connected.

If you have joined the domain and domain policies are applied correctly, I’m sure your server network profile will be ‘Domain network’.

Connected Network Profile

The real trick is to do a few registry modifications, but before doing that, you can try the below steps.

Open ‘Local Security Policy’ on the server and select the ‘Windows Defender Firewall…’ option as shown below. Then click on the properties of the settings.

Windows Defender Local Policy

This will open a box where you should turn off the Firewall for ‘Domain Profile’ and optionally for Private and Public profiles.

Off For Domain Profile

Once you make it off, it will show the status like below in Local Security Policy.

Status Of Firewall

Even though this screen shows that the firewall is turned off for the domain profile, but it will not work.

Still, the Windows defender will show that ‘Firewall is on’ for the domain network. By clicking the domain network in Windows Defender settings will not allow you to off the firewall because it was managed by the organization policy.

Active Network Profile

For your satisfaction, reboot the server and see if the above steps are useful. If not, let’s go to the final working solution.

Registry modification.

As mentioned earlier, this can be done by registry modification. Open the registry and access the below location.

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsFirewall
Before proceeding with anything, it is recommended to export the registry settings.

We have two options to achieve our goal here (Do any of it only).

Click on ‘Domain Profile’ and change the value from 1 to 0 for ‘EnableFirewall’. Restart the server to take effect.

Registry Value

OR….

Select the ‘Domain Profile’ and delete the entry completely. Reboot the server.

Delete Registry Key

With the reboot, you will notice that the firewall for the domain network profile is completely off. And for whatever reason you wanted to disable the firewall, now those services will communicate to this Windows 2019 server.

Disabled Firewall

This is the only simple and working method I found out to disable the Windows firewall on Windows 2019 server when managed by an organization/administrator in a domain environment. We do not need to modify the common group policy or give an exception for this server in policy that may require additional steps and implications at the domain level.

If any of the above solutions did not fix the Windows PC issues, we recommend downloading the below PC repair tool to identify and solve any PC Issues.
