Following the major Windows 11 24H2 kernel update, organizations running Check Point Endpoint Security VPN encountered critical connection failures: the client hung on "Connecting..." or threw error "Virtual Network Adapter Failed to Initialize". This issue stems from core changes in the Windows NDIS 6.8x networking stack conflicting with older Check Point virtual adapter drivers.
Root Cause Analysis
NDIS 6.80 & Core Isolation Driver Enforceability
Windows 11 24H2 enforces strict hypervisor-protected code integrity (HVCI) and updated NDIS driver bindings. Legacy Check Point drivers compiled for earlier Windows 10 releases fail signature verification, preventing the
Check Point Virtual Network Adapter For SecureClient from binding to physical Wi-Fi/Ethernet interfaces.
