MS NBNS extented implémentation (WINS) can map only Unique NetBIOS names to
unique IPadresses as hostnames. This is by design. Fortunately, many
NetBIOS names can be mapped to the same IP address, but this as
consequencies when using masquerading.

Furthermore, A PDC name (in fact a name like : ''MYDOMAIN       <1B>'' is
an unique name : this as consequencies when a PDC has multiple NIC and/or
IP adresses. Check MS knowledge base about this.
