We generally have two DHCP servers per site. The 3 day lease was instituted 2 or 3 years ago... maybe longer... when we had a very limited amount of IP addresses that could be assigned - basically ran out of them too often and had to clear out leases. We have more than enough now though. That's something to consider... raising DHCP lease times instead of lowering DNS scavenging times.

However that DHCP lease time seems short. How many DHCP servers do you have per site? With that lease time you should probably have a couple or a guarantee to be able to not have an outage of the server greater than 3 days or more preferably (to me) more than 1.5 days - lease half-life. About the only time I would recommend to anyone to go below 7-14 days on lease times is if they are trying to switch values for some of the networking components through DHCP. What is the idea behind the 3 day lease time? joe -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rick Kingslan Sent: Saturday, August 30, 2003 12:32 PM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] DNS Scavenging and DHCP Lease Expiration Times None that occur to me off the top of my head.

Our DHCP leases expire every 3 days. Are there any notable drawbacks or problems in changing the DNS scavenging time period to match the DHCP lease expiration time period? Thanks! Marcus
