Take it out back and beat it with a hammer. Tell the bean counters someone must have dropped it.

Infocus tech support was zero help with this. It will accept a DHCP assigned address with this mask, at least. I did try giving it a different IP address through DHCP but it didn't resolve problem.

Whenever the server is rebooted, it displays an error that there is a duplicate IP address on the network, and changes its own address to an auto-configured 169... address. The thing is it says it conflicts with the device having the IP address of 0.0.0.0., and gives the MAC address of the conflicting device. As far as I know this means it's a MAC address conflict. However the conflicting device does not share the IP address or the MAC address of the server. The other device happens to be an Infocus projector that gets it IP Address through a DHCP reservation. If I pull the cable on the projector and then reset the NIC on the server there are no problems. If I then plug the projector back in the two machines coexist happily until I have to reboot the server. Also, if I change the IP address on the server NIC without disconnecting the projector, the server is happy with its new address until the next time it reboots. At which point I can change it back to its original IP address and again all is well. So it detects an IP address conflict, but there is no duplicate IP address on the network, nor is the MAC address a duplicate. It only throws this error when the server boots, otherwise its fine. The server is a VM on Hyper-V and is a DC that also does DNS and DHCP. I've looked at DNS, WINS, DHCP and don't see anything amiss. Any suggestions on how to fix this?
