DNS showing same IP with 2 different machines

Windows 2003 server, running DNS and DHCP is showing the same ip address for 2 different machines.

These machines have wireless card and LAN cards (so they both have 2 ip address) but 1 ip address shows up as a DNS entry for both machines.

Before i have tried to ping the machine using Device name, but it doesnt resolve to the right IP. any ideas?

i have deleted the DNS entry and after reload its still show up the same.?
