NBNS is just the NetBIOS Name Service - short for NetBIOS. As you can see, it's a broadcast protocol.
This means that you need to update all the machines on your network that have static IPs with the new WINS server info - it's still trying to use WINS to the old server.
Another thing - make sure you update the WINS option on you DHCP server for all scopes and release/renew all DHCP clients after this.
Cheers! Let me know if you have any questions!

It depends on the version of clients on the network. If all Vista/Windows Server 2008 then no, not really.
If you're using XP or below and WS 2003, then it is highly recommended.
Cheers!
