Platí pro: Windows SBS 2003

Cause: The domain Group Policy settings are selected for Windows Firewall, but the local computer Group Policy setting is not configured.

Solution: This is expected. Both the local Group Policy setting and the domain Group Policy settings are displayed in the Windows Firewall Exceptions tab.
