5508 WLAN Controller ip conflict

I have a 5508 wlan controller for my organization wireless network and all machines that connect to the wireless network conflict with IP address 0.0.0.0 that has mac address 00-00-00-00-00-00.

All machines event viewer shows this error “The system detected an address conflict for IP address 0.0.0.0 with the system having network hardware address 00-00-00-00-00-00. Network operations on this system may be disrupted as a result.”

Pls help

you can try excluding the imp ip address so the dhcp server does not give out those. Also, try using small lease time..still not clear on the exact issue..
