So I've a test box running with Server 2008 R2 that is also setup as a DC, DNS, and DHCP server
The problem is wireless devices like say my Android phone.. initially it connects fine and gets an IP and works away, but the next day it'll be unable to get an address and I either have to manually delete the lease on the server or give it a manual IP (in both cases it then works fine again)
I've experimented with different lease times from the default 8 days, to longer, and shorter but still having issues. There's also wired clients to consider of course and these seem ok anyway.
Just wondering what others set the lease time to as I'm sure with wireless-enabled devices like Blackberrys and laptops etc being used it's probably a common problem.
Any feedback appreciated
