nmbd log spam

[deafen]

Sometime in the last couple months, I've started to see a ton of log messages from nmbd, specifically around things that it thinks should be sent to a WINS server. I am seeing it from both Mac and Windows clients, but not from all of them. They come in a couple flavors:

From a Windows 7 machine:

I am running a very simple network - workgroup-based (no AD), no WINS server, no directory services of any kind other than DNS provided by the router. Running 9.2.0-release. I'm not sure how or why this got started, and why it's only some machines that are causing the issues. Any insight would be appreciated.

I believe I have the same problem. However, I am trying to make freenas work as a WINS server. In my router DHCP settings I set the WINS server to the IP of the freenas. After that I started to get the same errors.

Try looking at the configured WINS server in your client machines
