I could have sworn that would have worked.
I tried the following
(and restarted the syslog via /sbin/service syslog restart)
# Suppress messages from samba.
For interests sake the messages I'm getting are below (I'm not concerned about the messages themselves, I can chase them up at my leisure via the samba logs)
Mar 18 09:58:29 SERVER nmbd: query_name_response: Multiple (2) responses received for a query on subnet xx.yy.z.zz for name DOMAIN<1d>.
Mar 18 09:58:29 SERVER nmbd: This response was from IP xx.yy.z.zz, reporting an IP address of xx.yy.z.zz.
What can I try next?
