FPCVpnQuarantineSettings

Internet Security and Acceleration Server 2004/2006 SDK

The FPCVpnQuarantineSettings object defines the virtual private network (VPN) quarantine settings.

The FPCVpnQuarantineSettings object is accessed through the QuarantineSettings property of an FPCVpnConfiguration object.

The VPN quarantine uses the Network Access Quarantine Control feature of Windows Server 2003 to prevent remote VPN clients from obtaining normal remote access after authentication 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 quarantine can be enabled by installing Remote Access Quarantine Agent (Rqs.exe) on the ISA Server computer and Remote Access Quarantine Client (Rqc.exe) on VPN clients. Rqc.exe runs as a notification component on the remote client computer, informing the Rqs.exe listener component running on the ISA Server that the client computer complies with security policy. Both of these tools are available in the Windows Server 2003 Resource Kit Tools. After Rqs.exe is installed, the Remote Access Quarantine Tool for ISA Server 2004 (RQSUtils.EXE) should be run on the ISA Server computer. This tool adds an RQS protocol definition on the ISA Server computer, creates an instance of the RQS service, and creates an access rule allowing the RQS protocol. 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.
