Within the NetBIOS-over-TCP protocols, a longer representation is used.<br><br>There are two levels of encoding. The first level maps a NetBIOS name into a domain system name. The second level maps the domain system name into the 'compressed' representation required for interaction with the domain name system.<br><br>This operation carries out the first level of encoding. See RFC 1001 for full details.";
