The FPCVpnConfiguration object defines the virtual private network (VPN) settings for an ISA Server computer that serves as a VPN gateway.
The VPN configuration includes VPN quarantine settings, which can be accessed through the QuarantineSettings property. A VPN quarantine uses the Network Access Quarantine Control feature of Windows Server 2003 to prevent remote VPN clients from obtaining normal remote access until the configuration of their systems has been examined by a server-provided script and validated as meeting the requirements of the organization's network policies. The connection to a remote VPN client can be closed if the time-out period elapses before the configuration is validated.
The clearing of VPN clients from a quarantine can be enabled by installing Remote Access Quarantine Agent (Rqs.exe) on the ISA Server computer and the Remote Access Quarantine Client utility (Rqc.exe) on VPN clients. Both of these utilities are available in the Microsoft Windows Server 2003 Resource Kit. Additional steps must also be performed. For detailed instructions on implementing the clearing of VPN clients from a quarantine, see VPN Roaming Clients in ISA Server 2004.
Alternatively, you can create a custom listener component that listens for messages from a matching notifier component running on quarantine-compatible remote access clients. These messages indicate that the scripts have been run successfully. Then your listening component can use the MprAdminConnectionRemoveQuarantine function to remove the quarantine restrictions from the remote access connections.
The FPCVpnConfiguration object is typically accessed through the VpnConfiguration property of an FPCNetworkConfiguration object.
