problems with OSX?

Hi Matt

What do you mean by "constantly"? Every minute, every hour? Or even  
more often?

We have a lot of OS X clients (in fact, our dhcp server is also  
running on an OS X box), but I have never seen anything like  
"constant" releasing/renewing. We have a lease time of 6hrs, and most  
clients renew reguarly after exactly 3 hrs. Some renew in an more  
irregular fashion (40min, then 4hrs, them 1hr 10mins), but I guess  
that's due to them being restarted or sleeping. The only time I have  
seen something like this was when I tried to assign a client an IP  
that was already in use by another machine (which was manually  
configured with a fixed IP).

Sorry not to be more helpful, but could you provide us with a little  
more information? Which version of OS X is running on the affected  
clients? Configuration of your DHCP server - anything special, maybe?
