I have an odd issue on some hosts (Windows XP and 7 and iOS X) after converting to DHCP reservations: I get an IP conflict message even though I know that there is no other device on the network using the machine's reserved IP addresses. The only way to resolve the issue is to delete the reservation and let the DCHP server dish out an address of its choosing.
If anyone knows what could be causing this issue (apart from an actual host on the network using the reserved IP address) I would be grateful to hear about it. As I said above, I am certain there's no other machine on the network using the reserved IP address.
Thanks,
Steve
