This is not a Samba limitation, this is by NetBIOS design, which Samba  
of course respects:

Look at this page:

"NetBIOS names are 16 octets in length and vary based on the  
particular implementation. Frequently, the 16th octet is used to  
designate a "type" similar to the use of ports in TCP/IP. It is called  
the NetBIOS Suffix (read below) or "resource type", and is used to  
tell other applications what type of services the system offers."

Looking at your smb.conf, it seems to me that you are mixing up  
NetBIOS domain names and FQDNs (Fully Qualified Domain Names). They  
are not the same thing and should be used in their proper place.
