Doesn't the box request a renewal of the least at 1/2 lease intervals? Eg: a 1 hour lease would result in a request from the box to renew the lease after 1/2 hour. If no renewal if received then the system will request another from the server after another 15 minutes. If it's still not renewed then another request for a renewal is sent after 7.5 minutes.......
This continues till the lease either expires or is renewed. I THINK this is correct.

Sent: Wednesday, August 24, 2005 6:40 PM To: CLUG General Subject: [clug-talk] Re: Help: Connectivity Loss at 6 Hours Tell the box to re-request another lease and set it for one hour...Then from another box(or the gateway) watch the traffic. See if the box does request another lease at the end of the hour and pay special attention to the sequence of request and response between the box and DHCP server... This will give you a clearer idea of the nature of the problem, rather than poking in the dark...
