DHCP msg in event viewer

I'm getting the following in Event Viewer aprox once per day. I'm not experiencing any network problems, my router is connected without issue. I'm just wondering if it's something I need to resolve, or should ignore.

"The IP address lease 192.168.0.2 for the Network Card with network address 00112F700EFE has been denied by the DHCP server 192.168.0.1 (The DHCP Server sent a DHCPNACK message)."

I'm using the Netgear DG834.

If things are working correctly, ignore it. I think it's just a timing issue with the NIC being initialised.
