Whilst name_status_find is meant for netbios, if you look at the code,
there is this near the top of the function:

	if (lp_disable_netbios()) {
		DEBUG(5,("name_status_find(%s#%02x): netbios is disabled\n",
					q_name, q_type));
		return False;
	}

Which to myself, means that if 'disable netbios = yes' is set in
smb.conf , then return false and log a message if the log level is 5 or
greater.

If 'disable netbios = yes' is set in smb.conf, then netbios shouldn't
be used by Samba and you shouldn't be having problems with it.

I think you need to give us a bit more detail:

What version of Windows server ?
What version of Samba are you using ?
What OS is Samba running on ?
Please post the output of 'testparm -s'
   
At the moment, all I can say is that it all works for myself, but I am
using Samba (with netbios turned off and nmbd not running) against a
Samba AD DC (again with netbios turned off and nbt turned off).
