NetBIOS domain name change causes Samba not to save and produces an error

[ZentyalNoob]

My current zentyal test setup works perfect except when I want to change the NetBIOS domain name from simply stating AD to RW. It is quite a simple change, but when I make the change Samba stops at 65% and then produces an error.

"Some modules reported error when saving changes . More information on the logs in /var/log/zentyal/"

The error below is repeated several times and I cannot get Samba to save the settings properly, so I get kicked out of the domain and cannot rejoin. Is there something I need to change before making this netbios name change? I looked around the forums and did not see a solution.

On Zentyal 3.3 community version, single server home environment, I've not been able to resolve this or get shares working.
I've ended up removing the file sharing module and installing standard samba and setting up my shares with minimal effort. I've not tried using the ldap users in the share ACLs but instead used the samba users I created.
