I'm not sure if this is helpful or not, but one of our other DHCP issues we run into is due to the route to the DHCP server being dropped. Example: On the PA, we have zone X which provides services to a particular set of clients. We then have zone Y which connects the main part of our network, including the DHCP server. Zone X router does a DHCP relay to the DHCP server through the PA. This works fine normally. However, sometimes, the switch between the PA and the router controlling our main network reboots. When that happens, our DHCP from zone X begins failing. Going into session browser on the PA shows that because the route to the DHCP server was lost when the PA dropped its OSPF connection to the main network router, the DHCP requests started being sent to the "Outside" zone and essentially the session just locks. When I delete that session, it starts going back the proper way and DHCP begins working again. It may be completely unrelated, but the session browser might be a good place to see anything odd happening. Regards Kevin
