The above shows the problem, you cannot use the realm name for the
netbios domain name (aka workgroup), or to put it another way, your
netbios domain name 'DUCK' cannot be the same as your realm 'DUCK'.
Is your dns domain really just 'duck' ?
If so, I think you need to consider changing it.
I suggest you read this:
You could use something like 'duck.tld', just don't use the TLD '.local'
