Configure Windows Firewall to Suppress Notifications When a Program Is Blocked

  • Article

 

Applies To: Windows Server 2012

To configure Windows Firewall to suppress the display of a notification when it blocks a program that tries to listen for network traffic and to prohibit locally defined rules, use the Windows Firewall with Advanced Security node in the Group Policy Management MMC snap-in.

Warning

If you choose to disable alerts and prohibit locally defined rules, then you must create firewall rules that allow your users’ programs to send and receive the required network traffic. If a firewall rule is missing, then the user does not receive any kind of warning, the network traffic is silently blocked, and the program might fail. We recommend that you do not enable these settings until you have created and tested the required rules.

Administrative credentials

To complete these procedures, you must be a member of the Domain Administrators group, or otherwise be delegated permissions to modify the GPOs.

To configure Windows Firewall to suppress the display of a notification for a blocked program and to ignore locally defined rules on Windows 8, Windows 7, Windows Vista, Windows Server 2012, Windows Server 2008 or Windows Server 2008 R2

  1. Open the Group Policy Management Console to Windows Firewall with Advanced Security.

    1. Click the tab that corresponds to the network location type.

    2. Under Settings, click Customize.

    3. Under Firewall settings, change Display a notification to No.

    4. Under Rule merging, change Apply local firewall rules to No.

    5. Although a connection security rule is not a firewall setting, you can also use this tab to prohibit locally defined connection security rules if you are planning to deploy IPsec rules as part of a server or domain isolation environment. Under Rule merging, change Apply local connection security rules to No.

    6. Click OK twice.
