hi David,

Please explain the complete scenario. Why is the router assigning reserved IP address to DHCP client with some other MAC address?

Thanks

Though the DHCP Network Hint feature initially struck as me as neat, it's been causing me some trouble in a personal WLAN setting running a Netgear WGR614v6 AP that uses the address reservation feature to dynamically allocate specific IPs to programmed MAC addresses.

With DHCP network hint enabled my Windows 7 machines would frequently end up with IP addresses actually reserved for other MAC addresses, and once they had obtained such an invalid IP address, it was quite difficult to convince them to actually request a new lease from the server (not to mention that with lots of non-matching assigned IP/MAC pairs the server would actually have problems assigning the correct IP as it would often be in use by another rogue Windows 7 system).

Disabling DHCP network hint resolved the problem (which thus of course never occured with Vista/XP systems).
