Removing Incorrect WINS record

So I have a Ubuntu 14.04 server that I'm trying to get to run as a Domain Controller for a set of Windows machines. I've set up a Bind9 DNS and it works fine, pinging the nameserver gives the correct IP: 192.168.0.3. However pinging the Netbios name gives 192.168.0.255 which is wrong, I saw a similar problem on the Unix and Linux stack exchange which said to run nmblookup -U 192.168.0.3 -R 'NETBIOS_NAME' This gives: 192.168.0.255 Arc 192.168.0.3 Arc 192.168.1.1 Arc The last two records are correct, but the first... I don't even know why or how that got there. I have no idea where that record is, my only WINS server is samba, but even if I set: wins support = no That entry (.255) doesn't go away.
