I take it that 'DOMAIN' is the placeholder for the correct NetBIOS 
domain name (aka workgroup).

Every Samba Unix domain member has a netbios name (the computers short 
hostname in capitals), but you do not need to set the 'netbios name = 
XXXXX' line in smb.conf, Samba will do it for you.

You also should not be using 'netbios aliases' in a Unix domain members 
smb.conf, you should set CNAME's in AD dns, Samba no longer uses NetBios 
or wins.
