3.1.4 Higher-Layer Triggered Events

See [MS-DHCPE] section 3.1.4 for the higher-layer triggered events for the DHCP client.

If DHCP enforcement is enabled for NAP on a DHCP client, the client MUST also trigger a DHCPDISCOVER or a DHCP Renew transaction, as specified in [RFC2131] section 3, whenever the system health state or configuration changes. Due to the vulnerability of DHCP, DHCP clients SHOULD NOT attempt to use NAP on unauthenticated wireless networks.
