SYMPTOMS
When you start or shut down your Windows XP-based computer, the Internet Connection Firewall (ICF) does not filter or provide firewall services. During the startup or shutdown process, users can connect to your computer or to any program or service that may be available. Note that other than these two times, ICF works correctly.



CAUSE
This issue occurs because during startup and shutdown, the user-mode service is not available. Because of this, the filter driver does not know which policy to enforce, and does not filter anything.
