Reserved IP address taken by unknown device

Hello All,

I have an odd issue, recently I moved all printers from a Windows server 2008 VM to a physical 2008 R2 server with Print management role installed. It all went smoothly except for one of the Multifunction printers which has decided not to print.

The strange thing I found is that I can ping the IP Address of the MFP when the LAN cable is out leading me to believe that another device has taken this IP. Strange thing is that this is a reserved address on our DHCP server. The MFP will print after I pull out and replace the power cable for 5 minutes then it will stop printing again shortly after, I have 2 of of these devices which are Olivetti MF250 Colour MFPs, the other one works fine and I can access the the web interface with no problem.

I have run every command I can think of to find out which host has this IP address, nbtstat -A <ipaddress>, NSLOOKUP <ipaddress> even tried traceroute. Our spice works can find it either. It's driving me nuts. This particular IP address is configured on the device so it must have this IP so I can't simply change it.

so in nut shell......

Moved printer from a VM, the MFP worked before then
Its now on a Physical box, 2008 R2 print server
I can ping the IP address and get a response when LAN cable is out
CMDs have  been no help.

If any one has any ideas I'd appreciate the help

Thanks


John
