Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

To restore Windows Firewall default settings

  1. Open Windows Firewall.

  2. Click the Advanced tab, click Restore Defaults, and then click OK.

Notes

  • To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure.

  • To start Windows Firewall, click Start, point to Control Panel, and then click Windows Firewall.

  • You can also use the netsh command with the firewall context to perform this procedure and configure other Windows Firewall settings.

  • If a Windows Firewall setting appears dimmed in the graphical user interface, and on the General tab, you see For your security, some settings are controlled by Group Policy, the setting might be managed by Group Policy. If all Windows Firewall settings appear dimmed, and on the General tab, you see You must be a computer administrator to change these settings, you do not have administrative rights to configure Windows Firewall.

  • Windows Firewall is not included in the original release of the Windows Server 2003 operating systems.

  • Restoring the default settings will undo all of the changes you have made to Windows Firewall. Restoring the default settings will also turn Windows Firewall on for all network connections, which might cause some programs to stop working. In addition, restoring the default settings might cause Internet Connection Sharing and Network Bridge to not work correctly.

  • Internet Connection Sharing and Network Bridge are not included in Windows Server 2003, Web Edition; Windows Server 2003, Datacenter Edition; and the Itanium-based versions of the original release of the Windows Server 2003 operating systems.
